@Dietmar I need to remember and practice because I don't remember exactly. pci - list all PCI devices For graphics card you need set register Command (4): 0007 mm xxyyzz04 7 -pci For PCI Bridge you need set register VGA Enable in Bridge Control (3E) (the bridge to which the graphics card is connected) mm xxyyzz3E 8 -pci xxyyzz is PCI bus dev func of PCI Bridge device https://forums.macrumors.com/threads/win7-x64-booting-natively-via-efi-no-bios-emulation.696523/post-14778765 https://forums.macrumors.com/threads/win7-x64-booting-natively-via-efi-no-bios-emulation.696523/post-14776170 This is example in my PC: 00 1C 04 - PCI bridge to which the graphics card is connected 04 00 00 - PCIe graphics card mm 001c043e 8 -pci VGA Enable mm 04000004 7 -pci I/O acces and Bus master For check changes: pci -i 00 1c 04 -b pci -i 04 00 00 -b To check bridge to which the graphics card is connected use: devtree -b and dh handle_number

Try set VGA Enable in UEFI Shell before run CSMWrap: https://www.betaarchive.com/forum/viewtopic.php?p=434759#p434759

@roytam1 github problem if try use @

@Dietmar You tried other cards? Best I use is AMD HD7450 with GOP+VBIOS or AMD HD6450 only VBIOS but I insert GOP to motherboard bios and now card works also in pure UEFI https://www.betaarchive.com/forum/viewtopic.php?p=471154#p471154 With this cards works all - passthrough in VMware ESXi or virt-manager QEMU KVM, XP 64-bit in pure UEFI, XP 32-bit with CSMWrap

With a PCIe Radeon R5 card you also have an XP desktop in 4-bit? How VBIOS is then used - check, for example, with SLIC ToolKit > C0000 memory dump. This is my radeon VBIOS when boot using CSMWrap:

What is the native resolution of the monitor connected to the graphics card? I noticed interesting things when we change the GOP resolution before running CSMWrap. You can change the resolution, for example, using UefiSeven 1.31 in the UefiSeven.ini file and boot the u7 without the .original.efi file - then the u7 will boot at the set resolution and return to the UEFI Shell because it does not find the original.efi file Now run CSMWrap runs at the same resolution as set by U7 (SeaBIOS probably also). I tested with winload.exe and in XP it boot in 800x600 but in the screen settings there are different resolutions to choose from - different depending on what resolution you set in U7. Unfortunately, changing the resolution restarts the computer.

NTFS partition must be created using diskpart from Win7 or newer for bootmgr load or change bootsector in WinPE: bootsect /nt60 C:\ or change in Bootice: @Dietmar Read also this: https://github.com/FlyGoat/CSMWrap/issues/46

@Dietmar I sent to email.

For the serial port to work you need to load the pciserial.efi and terminal.efi drivers in the UEFI Shell: load pciserial.efi terminal.efi Try my patched Longhorn 5472 winload.exe + bootmgr + BCD - the necessary files I seem to have already sent you. You need also fix BCD using bootice.exe https://msfn.org/board/topic/186793-csmwrap-boot-csm-on-uefi-only-systems/page/2/#findComment-1280116

I have but the old version: https://github.com/FlyGoat/CSMWrap/issues/14#issuecomment-2889051446

Yes, these drivers work 100% - I tested both 32-bit in XP 32-bit and 64-bit in XP 64-bit The same drivers also work in Win7

In that case, look for a support to the problem from the system manufacturer - good luck I don't want to post a tutorial on a forum that will disappear from the web in a moment like reboot.pro

@Klemper I have a question - is registration not working on the MDL forum? I don't want to explain once again what and how because that's how everything is described: https://forums.mydigitallife.net/threads/usb-3-xhci-driver-stack-for-windows-7.81934/page-18#post-1861262 My drivers work OK and tested on many computers. First time I've heard of drivers "killing the mobo"

@roytam1 Best USB3 drivers for XP - AMD by daniel fixed by me - I use them in my XP 32 and 64-bit tutorials on MDL. Also works fixed by me from George King 6.2.9200.21180 - I used them in tutorials before but they have a slight problem: https://forums.mydigitallife.net/threads/winxp-64-bit-on-a-modern-pc-iso-boot-wim-install-wim.88435/page-7#post-1868985 Everything is on MDL in my tutorials and other topics - just register.

What problem to make an account?

No

@Dietmar Have you checked if there is any debug information in Putty via COM port after load drivers pciserial.efi & terminal.efi ?

@Dietmar No, links not works but as far as I know DUET is a UEFI bios and there is no such file because it doesn't make sense - to run UEFI bios on UEFI bios

I wonder if every UEFI no-CSM bios is missing table for all the legacy Interrups?

Wait, wait, wait - after all, OVMF_CODE-pure-efi.fd bios doesn't have these modules and CSMWrap works

Maybe instead of adding the code to CSMWrap you can insert these modules into the motherboard no-CSM bios using UEFITool ??

Heh.. this is not CSM related: InitializeBochsGraphicsMode

@Dietmar If you are right then the CSMWrap project is useless

But CSMWrap.efi works OK on this UEFI64 firmware (works also 32-bit version OVMF 32-bit): https://msfn.org/board/topic/186793-csmwrap-boot-csm-on-uefi-only-systems/#findComment-1280103 How do you explain it?
