  1. Hi, Seems you are messed with arguments/stack at return, "ret x" must take return adress to parent, but it take from stack random arg and jump to it :)
  2. Hi Ximonite, any source code available ? or all functions was ripped as disassembly ?
  3. win32k declare own ring3->ring0 service table for user32 and gdi32 see KeAddSystemServiceTable() inside win32k
  4. security_cookie is constant 0x4EE640BB inside file
  5. NTOSKRNL Emu_Extender Library of missing functions for Windows XP/2003/Vista/7 NTOSKRNL.EXE Project is intended to help in porting drivers from Windows 7/8/8.1/10 for work with Windows XP/2003/Vista/7 How-To: 1) Compile sources to make ntoskrn8.sys 2) Make corrections to xxx.sys so that it loads ntoskrn8.sys instead of the original ntoskrnl.exe 3) Place ntoskrn8.sys to X:/Windows/sytem32/drivers/ folder Compiling: 1) Install Windows 7 DDK v7.1.0 (download from Microsoft site) 1a) Original DDK header files has mistake with definintion of MmAllocateContiguousMemorySpecifyCacheNode, apply fix: \WinDDK\Win7\inc\ddk\ntddk.h: \WinDDK\Win7\inc\ddk\wdm.h: #if (NTDDI_VERSION >= NTDDI_WIN2K) typedef ULONG NODE_REQUIREMENT; to: #if (NTDDI_VERSION >= NTDDI_VISTA) typedef ULONG NODE_REQUIREMENT; 2) Download project files to any local folder git clone https://github.com/MovAX0xDEAD/NTOSKRNL_Emu 3) Select Target OS Keep in mind that depending on the target operating system the way of exporting the functions changes, if a function already exists in the kernel it will be simply redirected without injecting emulation code 4) Run shell Start Menu\Programs\Windows Driver Kits\Win7 7600.16385.1\Build Environments\Windows XXX\YYY Free Build Environment XXX - target OS, YYY - target CPU, 5) In shell change current directory to local project folder 6) Use shell command BLD to compile project 7) Compiled ntoskrn8.sys will be in ntoskrn8/objfre_XXX_x86/YYY folder STORPORT Windows 7 Emu_Extender This is Library of missing functions for Windows 7 STORPORT.SYS to emulate Windows 8 STORPORT.SYS How-To: 1) Compile ntoskrnl Emu_Extender 2) Place storpor8.sys to X:/Windows/system32/drivers/ folder 3) Make corrections to target xxx.sys so that it loads storpor8.sys instead of the original storport.sys Ported drivers: WDF 1.11 for Windows XP/2003 x32 Last version for Windows XP/2003 is 1.9, but possible to backport 1.11 version: 1) Get files from Windows 7 Updates: WDF01000.SYS v 1.11.9200.20755 WdfLdr.sys v 1.11.9200.16384 2) In WDF01000.SYS replace string ntoskrnl.exe to ntoskrn8.sys in import section, now WDF01000.SYS will import all kernel functions only from Emu_Extender 3) Recalc checksum If need coexist with original WDF1.9 drivers: 4) Rename WDF01000.SYS->WDF01_W8.SYS, WdfLdr.sys->WdfLdr8.sys 5) In WDF01_W8.SYS replace string WdfLdr.sys to WdfLdr8.sys in import section 6) In WdfLdr8.sys replace unicode string \Registry\Machine\System\CurrentControlSet\Services\Wdf%02d000 to \Registry\Machine\System\CurrentControlSet\Services\Wdf%02d_w8 7) In WdfLdr8.sys replace hex pattern **F6 78 1B F6** to **F6 EB 1B F6** 8) In ported driver xxx.sys replace string WdfLdr.sys to WdfLdr8.sys in import section 9) In .INF of ported driver add creating new service: AddService=WDF01_W8,, WDF.AddService .... [WDF.AddService] DisplayName = "Windows Driver Framework v1.11 for XP/2003" ServiceType = 1 ; SERVICE_KERNEL_DRIVER StartType = 3 ; SERVICE_DEMAND_START ErrorControl = 1 ; SERVICE_ERROR_NORMAL ServiceBinary = %12%\WDF01_W8.SYS LoadOrderGroup = Base Windows 7's Storport.sys for Windows XP x32 Storport was released only for Windows 2003, but possible to backport Windows 7 version: 1) Get files from Windows 7 Updates (KB3125574): storport.sys v 6.1.7600.23403 2) In storport.sys replace string ntoskrnl.exe to ntoskrn8.sys in import section, now storport.sys will import all kernel functions only from Emu_Extender 3) Storport uses MSI interrupts, need to force use only legacy/compatible interrupts replace hex pattern **8B 8E 3C 01 00** to **B9 00 00 00 90** 4) Recalc checksum Windows 7's NVMe driver for Windows XP x32 1) Get files from Windows 7 Updates (KB3125574): stornvme.sys v 6.1.7600.23403 2) MS Win7 NVMe driver require Win7 Storport.sys, use backported one Windows 8's USB3 driver for Windows XP x32 1) Get required files from Windows 8: ucx01000.sys usbhub3.sys usbxhci.sys wpprecorder.sys usbd.sys from Vista Beta/Longhorn 5456.5: ksecdd.sys 2) In files ucx01000.sys, usbhub3.sys, usbxhci.sys, wpprecorder.sys, usbd.sys change security_cookie to random value 3) In files ucx01000.sys, usbhub3.sys, usbxhci.sys, ksecdd.sys replace string name "ntoskrnl.exe" to "ntoskrn8.sys' in import section, now *.sys will import kernel functions only from Emu_Extender 4) Rename ksecdd.sys->ksecd8.sys, usbd.sys->usbd_w8.sys 5) In usbhub3.sys replace string name "ksecdd.sys" to "ksecd8.sys' in import section 6) In usbhub3.sys replace string name "usbd.sys" to "usbd_w8.sys' in import section, 7) recalc checksum Windows 8’s STORAHCI driver for Windows XP x32 STORAHCI driver requires storport.sys from Windows 8, but possible to use storport.sys from Windows 7 storport.sys from Windows 7 more compatible with Windows Xp/2003 because it still call required PoStartNextPowerIrp when processing power IRPs. MS removed calls to PoStartNextPowerIrp in Windows 8’s storport.sys, without this call Windows XP/2003 kernel cannot finish current power IRP and start next IRP, also it generate BSOD (0x0000009F) Take attention: Win8’s STORAHCI + Win7’s STORPORT have significal performance drop and high CPU usage, there is no fix yet 1) Get files from Windows 8 (): storahci.sys v 6.2.9200.16384 2) In storahci.sys replace string storport.sys to ntoskrn8.sys in import section, now storahci.sys will import all storport functions only from Emu_Extender 3) storahci.sys was compiled with Windows 8 DDK’s storport.h and writes to new fields of _PORTCONFIGURATION_INFORMATION, these fields not exist in Windows 7’s storport.sys Need to skip these writes to avoid damaging structures in memory: replace hex pattern 83 A6 C8 00 00 00 00 to 90 90 90 90 90 90 90 replace hex pattern 83 8E CC 00 00 00 03 to 90 90 90 90 90 90 90 If you compile storahci from sources (from Windows 8 DDK Samples), comment two lines: ConfigInfo->BusResetHoldTime = 0; ConfigInfo->FeatureSupport |= STOR_ADAPTER_FEATURE_STOP_UNIT_DURING_POWER_DOWN; 4) In storahci.sys change security_cookie to random value 5) Recalc checksum Windows 7’s MSAHCI driver for Windows XP x32 1) Get files from Windows 7 Updates(KB3125574): atapi.sys v 6.1.7600.23403 ataport.sys v 6.1.7600.23403 msahci.sys v 6.1.7600.23403 pciidex.sys v 6.1.7600.23403 2) In ataport.sys, pciidex.sys replace string ntoskrnl.exe to ntoskrn8.sys in import section, now these *.sys will import all kernel functions only from Emu_Extender 3) pciidex.sys uses MS Internal/Undocumented HalDispatchTable way to call functions from Kernel/HAL, For Windows XP/2003 x32 need to use compatible variant: replace hex pattern FF 50 3C to FF 50 40 same in asm code: mov eax, ds:HalDispatchTable ... call dword ptr [eax+3Ch] => call dword ptr [eax+40h] 4) Recalc checksum 5) MSHDC.INF from Windows 7 may conflict with original mshdc.inf from Windows XP/2003 For example msahci enumerates IDE/SATA channels as InternalIDEChannel and compatible ID as *PNP0600. Original mshdc.inf for *PNP0600 will install wrong Standard IDE/ESDI Hard Disk Controller driver Intel RSTe (Enterprise/Premium) AHCI/RAID driver 4.7.0.1098 for Windows XP/2003 Intel RST AHCI/RAID drivers (any version, last compatible is 15.9.8.1050) for Windows XP/2003 These drivers require storport.sys from Windows 7, use backported version. 1) In file iaStorA.sys or iaStorAC.sys replace string “ntoskrnl.exe” to “ntoskrn8.sys” in import section (do not change second string “NTOSKRNL.exe”) now these *.sys will import kernel functions only from Emu_Extender 3) Recalc checksum Implemented Func List v6: _chkstk _i64toa_s _i64tow_s _itoa_s _itow_s _makepath_s _snprintf_s _snscanf_s _snwprintf_s _snwscanf_s _splitpath_s _strnset_s _strset_s _strtoui64 _swprintf _ui64toa_s _ui64tow_s _ultoa_s _ultow_s _vsnprintf_s _vsnwprintf_s _vswprintf _wcsnset_s _wcsset_s _wmakepath_s _wsplitpath_s _wtoi _wtol DllInitialize DllUnload EmClientQueryRuleState EtwActivityIdControl EtwEventEnabled EtwProviderEnabled EtwRegister EtwUnregister EtwWrite EtwWriteString EtwWriteTransfer ExAcquireRundownProtectionCacheAware ExAcquireRundownProtectionCacheAwareEx ExAllocateCacheAwareRundownProtection ExEnterCriticalRegionAndAcquireResourceExclusive ExFreeCacheAwareRundownProtection ExGetFirmwareEnvironmentVariable ExInitializeRundownProtectionCacheAware ExReInitializeRundownProtectionCacheAware ExReleaseResourceAndLeaveCriticalRegion ExReleaseRundownProtectionCacheAware ExReleaseRundownProtectionCacheAwareEx ExRundownCompletedCacheAware ExSetFirmwareEnvironmentVariable ExSizeOfRundownProtectionCacheAware ExWaitForRundownProtectionReleaseCacheAware IoAllocateSfioStreamIdentifier IoConnectInterruptEx IoDisconnectInterruptEx IoFreeSfioStreamIdentifier IoFreeWorkItem IoGetActivityIdIrp IoGetAffinityInterrupt IoGetDevicePropertyData IoGetIoPriorityHint IoGetSfioStreamIdentifier IoInitializeWorkItem IoQueueWorkItemEx IoSetActivityIdIrp IoSetDevicePropertyData IoSizeofWorkItem IoUninitializeWorkItem IoUnregisterPlugPlayNotificationEx KdRefreshDebuggerNotPresent KeAcquireGuardedMutex KeAcquireGuardedMutexUnsafe KeEnterGuardedRegion KeGetCurrentNodeNumber KeGetCurrentProcessorNumberEx KeGetProcessorIndexFromNumber KeGetProcessorNumberFromIndex KeInitializeGuardedMutex KeLeaveGuardedRegion KeQueryActiveGroupCount KeQueryActiveProcessorCount KeQueryActiveProcessorCountEx KeQueryDpcWatchdogInformation KeQueryGroupAffinity KeQueryHighestNodeNumber KeQueryLogicalProcessorRelationship KeQueryMaximumGroupCount KeQueryMaximumProcessorCount KeQueryMaximumProcessorCountEx KeQueryNodeActiveAffinity KeReleaseGuardedMutex KeReleaseGuardedMutexUnsafe KeRevertToUserAffinityThreadEx KeRevertToUserGroupAffinityThread KeSetCoalescableTimer KeSetSystemAffinityThreadEx KeSetSystemGroupAffinityThread KeSetTargetProcessorDpcEx KeTryToAcquireGuardedMutex LpcReplyWaitReplyPort LpcSendWaitReceivePort memcpy_s memmove_s MmAllocateContiguousMemorySpecifyCacheNode MmAllocateContiguousNodeMemory MmGetSystemRoutineAddress ObfDereferenceObjectWithTag ObfReferenceObjectWithTag PcwAddInstance PcwCloseInstance PcwCreateInstance PcwRegister PcwUnregister PoDisableSleepStates PoEndDeviceBusy PoGetSystemWake PoRegisterPowerSettingCallback PoSetDeviceBusyEx PoSetSystemWake PoStartDeviceBusy PoUnregisterPowerSettingCallback PsSetCreateProcessNotifyRoutineEx RtlCheckPortableOperatingSystem RtlIsNtDdiVersionAvailable RtlQueryRegistryValuesEx RtlSetPortableOperatingSystem SeReportSecurityEventWithSubCategory SeSetAuditParameter SeSetAuthorizationCallbacks sprintf_s sscanf_s strcat_s strcpy_s strncat_s strncpy_s strnlen strtok_s swprintf_s swscanf_s vsprintf_s vswprintf_s wcscat_s wcscpy_s wcsncat_s wcsncpy_s wcsnlen wcstoul ZwAlpcConnectPort ZwAlpcSendWaitReceivePort Download Binaries https://github.com/MovAX0xDEAD/NTOSKRNL_Emu/releases Download Sources https://github.com/MovAX0xDEAD/NTOSKRNL_Emu
  6. Dedicated to fans of windows XP/2003 running on moderm (Acpi 2.0) PC Main purpose of patcher is help with eliminate/fixing Acpi 2.0 opcodes and 64-bit fields/regions/math without touching bios. Patch modify acpi tables every time when os start, it change current state of acpi tables in RAM memory (Bios load tables from flash chips to ram). Patcher works only with CSM (compatibility) mode, it will never works in UEFI boot mode. Using: 1) All custom files must named in old "8.3" DOS way ! 2) Create folder "ACPI_PAT" at root of you boot drive where installed target OS, this folder is place for storing all custom files (except bootloader) 3) Replace original bootloader (NTLDR for windows 2000/2003/XP, BOOTMGR for Vista/7/8/10, GRLDR for grub4dos) with patcher, original bootloader save as "xpldr" in ACPI_PAT folder 4) Place acpi_pat.img at ACPI_PAT folder 5) Place main configuration file ACPI_PAT.CFG: [DSDT] reload.bin bnum_fix.dif iotr_fix.dif,201904 test1.dif test2.hex [SSDT1] ; patch1 ;SSDT_FI1.HEX [SSDT3] ; patch 3 ;SSDT_FI3.HEX [SSDT*] # universal ssdt patch #SSDT_UNI.HEX [FACS] ;APIC_FIX.HEX [DSDT] [SSDT] - name of acpi table, only 4 chars !!! [SSDT3] - patch 3rd ssdt table, order of the ssdt table is determined by its position in the rsdt/xsdt tables [SSDT*] - special name to modify all ssdt tables ; patch1 - comments start with ";" or "#" reload.bin - BIN override table from binary file bnum_fix.dif - DIF is text format for GNU Patch iotr_fix.dif,201904 - DIF format with forcing iasl compiler version test2.hex - HEX is text format of "Find&Replace" hex strings 6) Order of applying patches is up-to-down, better to place first .bin patch, then .dif or .hex 7) Example of .hex format: ; comment 706869637320/706869637420 ;without spaces 70 68 69 63 73 20 / 70 68 69 63 74 20 ;with spaces, more readable 70 68 69 63 73 20 - hex string to find 70 68 69 63 74 20 - hex string to replace you can increase/decrease count of replaced bytes, size of table will be changed dynamicaly 8) Patcher supplied with 3 versions of iasl compiler/decompiler: IA201604.EXE IA201612.EXE IA201904.EXE These versions are equivalent of 20160422, 20161222, 20190405 at acpica.org Default version for processing dsdt/ssdt tables maded before 2016-12-31 is IA201612.EXE, for later dates is IA201904.EXE. You can also use your own version (DOS VERSION, compile yourself from acpica sources), name it "iaXXXX.exe" and place inside EXE.7z archive on floppy image. 9) Examples of .dif format: Fix BNUM Decompiling Bug: --- DSDT.dsl +++ DSDT.dsl @@ -1,1 +1,0 @@ - External (BNUM, UnknownObj) Fix Resource conflicting on Windows XP for Gigabyte H110-HD2 bioses: --- DSDT.dsl +++ DSDT.dsl @@ -1,36 +1,13 @@ AMI1 = ITA1 /* \ITA1 */ AMA1 = ITA1 /* \ITA1 */ AMI2 = ITA2 /* \ITA2 */ AMA2 = ITA2 /* \ITA2 */ AMI3 = ITA3 /* \ITA3 */ AMA3 = ITA3 /* \ITA3 */ - If ((ITS0 == One)) - { - ConcatenateResTemplate (Local0, BUF0, Local1) - Local0 = Local1 - } - - If ((ITS1 == One)) - { - ConcatenateResTemplate (Local0, BUF1, Local1) - Local0 = Local1 - } - - If ((ITS2 == One)) - { - ConcatenateResTemplate (Local0, BUF2, Local1) - Local0 = Local1 - } - - If ((ITS3 == One)) - { - ConcatenateResTemplate (Local0, BUF3, Local1) - Local0 = Local1 - } Return (Local0) } } } Scope (_SB.PCI0.LPCB) Patches generated by invoking (you can change/remove "-u6" option) Diff : diff -u6 --strip-trailing-cr OLD.DSL NEW.DSL > my_patch.dif Keep in mind that different versions of the compiler generate different versions of the ASL text. So context of .dif file is in most cases bound to specific version of the compiler 10) If using .dif patches, need additional file external.txt this is text format for using iasl.exe decompiler "-fe" option like this: External (AL6F, MethodObj, 0) External (HLVT, MethodObj, 0) External (P0L6, MethodObj, 0) External (P1L6, MethodObj, 0) External (P2L6, MethodObj, 0) External (PS0X, MethodObj, 0) External (PS2X, MethodObj, 0) External (PS3X, MethodObj, 0) External (_SB_.PCI0.GFX0.IUEH, MethodObj, 1) External (_SB_.PCI0.GFX0.GSCI, MethodObj, 0) External (_SB_.PCI0.PAUD.PUAM, MethodObj, 0) External (_SB_.PCI0.PEG0.HPME, MethodObj, 0) External (_SB_.PCI0.PEG1.HPME, MethodObj, 0) External (_SB_.PCI0.PEG2.HPME, MethodObj, 0) External (_SB_.PCI0.XHC_.DUAM, MethodObj, 0) External (_SB_.PCI0.XHC_.RHUB.INIR, MethodObj, 0) External (_SB_.PCI0.SAT0.SDSM, MethodObj, 4) External (MDBG, MethodObj, 1) External (_SB_.TPM_.PTS_, MethodObj, 1) 11) If using .dif patches, may be need additional file ignores.txt this is text format for filter iasl.exe decompiler errors, example of file: [BNUM] Namespace lookup failure, AE_ALREADY_EXISTS Many kabylake/coffelake bioses created with uncorrected asl code around BNUM fileld, when you decompile it, you will get "ACPI Error: [BNUM] Namespace lookup failure, AE_ALREADY_EXISTS (20161222/dswload-390)" error. With ignores.txt possible to filter/ignore these errors 12) When using .bin files, take care about override DSDT/SSDT tables, "template" from BIOS image is bad choice for such files. Bios patch some parts inside table before deploying to OS (bios usualy set absolute adresses). In this case run OS and save tables from runned state.
