@reboot12 I changed the original value in this Bios 09 07 04 00 00 00 00 ==> 09 07 03 00 20 00 01 0x4BF11 Form: CSM Configuration, FormId: 0x29AB {01 86 AB 29 15 21} 0x4BF17 Subtitle: Statement.Prompt: Compatibility Support Module Configuration, Flags: 0x0 {02 87 17 21 00 00 00} 0x4BF1E End {29 02} 0x4BF20 Subtitle: Statement.Prompt: , Flags: 0x0 {02 87 02 00 00 00 00} 0x4BF27 End {29 02} 0x4BF29 Suppress If {0A 82} 0x4BF2B QuestionId: 0x11F0 equals value 0x1 {12 06 F0 11 01 00} 0x4BF31 One Of: CSM, VarStoreInfo (VarOffset/VarName): 0xCBE, VarStore: 0x1, QuestionId: 0x561, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 2A 21 2B 21 61 05 01 00 BE 0C 10 10 00 01 00} 0x4BF42 Default: DefaultId: 0x0, Value (8 bit): 0x0 {5B 06 00 00 00 00} 0x4BF48 One Of Option: Disabled, Value (8 bit): 0x0 {09 07 04 00 00 00 00} 0x4BF4F One Of Option: Enabled, Value (8 bit): 0x1 (default MFG) {09 07 03 00 20 00 01} 0x4BF56 End One Of {29 02} and flash with EEpromer. Compi starts, but still no CSM can be choosen in Bios Dietmar PS: This is the modded Bios. Via normal Bios flash I was told, that Secure Flash failed, so EEpromer. https://ufile.io/x09np3zv

@reboot12 Can you make a try to unlock my Bios Dietmar https://ufile.io/aljnb4wv

Hi, is there a way to use UEFITool, for to unlock this AMI Bios? Or can the Bios direct been edited (Amitse, CFG Lock ?) with Ida Pro for to enable CSM Dietmar

@reboot12 How to log in into this chat Dietmar EDIT: Ok, I am there, as diderius6 .

@reboot12 No. I found only this: Launch EFI Shell from Filesystem device Dietmar

@reboot12 I did this already. But there is also no possibility in this Bios, to disable the onboard (cpu) graphic. But I can see Bios on screen with my external Geforce GT 730 card Dietmar

@reboot12 Hi, you are much better than me with this tools. Can you make a try for me for this Bios, thanks a lot Dietmar https://ufile.io/aljnb4wv

Hi, on the ASROCK N100DC-ITX I cant enable CSM in Bios. Crazy, I saw webside with this Motherboard, where in Bios you can select CSM. But in version 1.06, which comes with my board, no CSM selectable in Bios even there is CSM core as you can see with UEFI tool Dietmar PS: I saw this board also with Bios 1.10. But I dont know, how to get this. On Asrock website there is only the 1.06 Bios listed. EDIT: Now I think, no CSM in Bios because of the integrated iGPU. But how to disable this?

@reboot12 I noticed this behavior also on XP SP3. Yepp, something in registry changed. Because of this, I always make a copy of the whole folder Windows\system32 Dietmar

Hi, I just buy a new board ASROCK N100DC-ITX . It seems to have full XP support: CSM in Bios (I just check), Lan Realtek RTL8111H , Sound Realtek ALC897, Serial, USB2,3, nvme, Sata, PS/2, VGA, HDMI. The Serial port is the classic one, which means, that you can have a lot of fun with experimenting with it. And you can put an PCI-e graphik card into it, but only PCIe 3.0 x4 (only the Asrock N100M has PCIe 3.0 x16 Slot). It has Mini-ITX formfactor. Power consumption is 6(!)Watt and it is faster than my board for daily use with an i920 cpu. Passiv cooled. You need a 19V power supply for it (any notebook, even 12V should work). I will report soon Dietmar EDIT: I just check, that my Zotac GT 730 with PCIe 3.0 x16 connector fits and works even in a PCIe 3.0 x1 slot.

@roytam1 I cant register at discord nor your invitation works. Can you make a try, for to ask those people from 86box, to integrate this AWARD Bios from 2001 for the Shuttle Hot 433 vers. 1-3? mio.bin https://ufile.io/trzn0n6x Dietmar

@roytam1 Do you have a version of 86box, where this Bios from 2001 from Award for the Shuttle Hot 433 vers. 1-3 is integrated Dietmar

@roytam1 The original Bios for the Shuttle Hot 433 vers. 1..3 is from AMI. My modded 2001 Bios is from Award. The Bios is hard coded, so just change the name will never work. I can ask at git, for to integrate my Bios also Dietmar

@roytam1 I will test soon. Just now I install XP SP3 via your new english version. Full install lasts 4 hours. All works at once. Now I have XP SP3 on the AMD 486 and 133 MHZ, with sound and network Dietmar EDIT: With the AMD cpu overclocked to 160MHZ, the boottime of this XP SP3 to full desktop is 90sec.

@roytam1 Please tell me, which Bios file you where replace with my mio.bin and what name you use for my bios after Dietmar

@roytam1 I tried this, but get only a lot noise at start. No enumerating of memory. I think, that those roms are hard wired Dietmar

Hi, until now, I do all my tests on real hardware: The 486 Shuttle Hot 433 board, vers. 1..3 with 1024kB Cache and 256MB Ram. There I flashed the Bios from Award 2001(!) . It has a mod, for to disable the PS/2-mouse by default. mio.bin https://ufile.io/trzn0n6x Now I try to use the nice Emulator for x86 cpus https://github.com/86Box/86Box Is there a way, to add this mio.bin Bios to the 86Box? Because this Bios allows boot from Cdrom and large harddisks Dietmar PS: By the way, which is the last version of this Emulator, that works under XP SP3?

@roytam1 Oh, thanks, I am going to test. https://www.youtube.com/watch?v=zqsKbE0qH2I Just I read this https://www.pcgameshardware.de/Windows-Software-277633/News/Intel-i486-CPU-XP-1447805/ https://www.xda-developers.com/windows-xp-running-cpu-ten-years-older-itself/ https://www.tomshardware.com/software/windows/enthusiast-gets-windows-xp-running-on-an-i486 https://www.reddit.com/r/windowsxp/comments/1ctlglw/windows_xp_finally_works_on_486_processors/ https://itc.ua/en/news/a-combination-of-two-eras-windows-xp-launched-on-intel-i486-processor/ Do you have an idea, why the speed on a HD is so slow and using the PCI-slots with PCI to IDE/Sata is even more slow Dietmar

@user57 There must be something going complete wrong, using the PCI bus for installation of XP SP3 in compare with the original implemented IDE slots on the Shuttle Hot 433 board with 486 cpu. For the first TXT-Setup of XP I need about 45 min with the IDE slots, same cpu. With a PCI to IDE or PCI to Sata card, which should have full performance of 132 MByte/sec of the PCI bus (33 MHZ, 32 bit with 32 bit=4*8bit, gives 132 MByte/sec). But Now I need about 9(!) hours for the same TXT mode. This is a factor of 12 compared to the original IDE slots. So, the real speed of the PCI Bus is not 132 Mbyte/sec but for sure less than 11 MByte/sec, even the connected Sata or IDE harddisk is about 60 MByte/sec. And the PCI cards fulfill all to be faster than 132 MByte/sec Dietmar EDIT: The speed of this PCI bus is less than an original CD-ROM with speed 1, means 150Kb/s. Whole install of XP via Floppy disk with 200kB/sec would be faster..

Now I also succeed to install XP SP3 on the Shuttle Hot 433 board to a 486 cpu using the Dawicontrol DC-150, with newest flashed Bios for NON-Raid modus. This card is a PCI to Sata card, this means for the very first time I can boot XP SP3 for a 486 cpu via a fast Sata HD, nice Dietmar EDIT: Strange, during install via PCI to IDE/Sata card the install lasts much longer than with the integrated IDE ports?! A HD speed test with CrystalDiskMark5 using the integrated IDE ports, always crashes. I hope, that I can get some valid results via the PCI cards. EDIT2: Oh..crazy, the Bios puts in Standard Settings the speed of the PCI bus to halve of its original value..

@roytam1 After soso many fails I succeed to install XP SP3 to the Shuttle Hot 433 board with 486 cpu via an PCI slot using the PCI to IDE controller card Dawicontrol DC-133 and fresh flashed Bios from Silicon https://ufile.io/c41pi7rw Videocard is in Slot 1 (near to the ram) and DC-133 card is in 3. slot (near to the ISA). Until now I use a 8GB IDE harddisk but this I will change soon against an SSD via an IDE adapter Dietmar EDIT: The jumper for RAID I put away from the DC-133 card. The jumper for Bios Rom I set.

I tested about 20 different PCI to IDE/Sata cards with own Bios Rom. I flash a lot with EEProm writer. Always after this procedure I can see the connected HD or CD-Rom drive or both at boot time. But I never succeed with booting XP SP3 via any of this cards on the Shuttle Hot 433 board with 486 cpu. Also I cant install XP SP3 via any of this cards. Before I have to hit F8, I always get Bsod 0x7B, even the driver for this harddisk is to 100% correct and there. So I start to think, that the Bios of this board is faulty as much as possible or it is even impossible to boot via any of the PCI slots of this board. Only the own 2 integrated IDE slots work and the Floppy connector Dietmar

@Damnation May be, that IDE works, but I need for XP the boot Rom. Just now I order from ebay a card Dawicontrol DC-150, which has an own Bios Rom. https://www.ebay.de/itm/404890659301 On next weekend I make also a try with flashing another Bios to the Shuttle Hot 433 board, because my intuition tells me, that it is not normal that ALL PCI cards fail Dietmar EDIT: I found the driver together with the Bios for this card. nr for the NON-Raid version. Because in description they wrote, that driver and Bios from this card have to match. With my EEprom writer TL866 II plus it is easy for this Bios chip. dc150_nr.zip https://ufile.io/v3omq3sk

@Damnation I tested this card only for to boot XP SP3 on this 486 board Shuttle Hot 433, and there also no IDE Dietmar

@Damnation I have this card. No Rom, no boot message, just nothing on the Shuttle Hot 433 board for 486 cpu Dietmar PS: May be this happens, because no Bios Sata driver is integrated in the Bios from that Shuttle board.
