May 20, 20242 yr Author @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.

May 20, 20242 yr All links to Windows OS ISO have been removed. Do not post links to the ISO on the forum.
May 20, 20242 yr Author @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

May 21, 20242 yr Author @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
May 21, 20242 yr Author @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 Edited May 21, 20242 yr by Dietmar
May 25, 20242 yr I realise I'm very late and you've already solved it, but someone on vogons found this nugget of info: https://www.geoffchappell.com/studies/windows/km/cpu/cx8.htm Specifically : "In the early days of Windows NT, however, not all the extant processors implemented the cmpxchg8b instruction. In versions before 5.1, every function that uses the instruction has an alternate coding for processors that do not support the instruction. Very early during its initialisation, the kernel checks whether the boot processor supports the cmpxchg8b instruction. If the support is missing, the kernel patches jmp instructions at the start of each of those functions to redirect execution to their alternates. Conversely, if the boot processor does support the instruction, and the functions are left unpatched, then the kernel requires that all processors support the instruction, under pain of the bug check"
May 25, 20242 yr I haven’t posted in years. Found this thread from Slashdot. Just wanted to swing through and say how awesome this is.
May 30, 20242 yr Congratulations Dietmar. You made it to the news. "How to run Windows XP on an i486" (German) https://www.golem.de/news/betriebssystem-retrofit-wie-windows-xp-auf-den-i486-kommt-2405-185471.html Now you will be famous.
June 20, 20242 yr First, this is fantastic and I've been waiting to see XP patched for the 486 for a very long time! However, I have a problem installing. I have a Shuttle HOT-433 v1-3 motherboard with the 2001 Award BIOS. It has 128 MB of RAM, 512 KB cache and a 486 DX4/100. I can boot the patched ISO on the machine, and setup proceeds through the first section where it loads a lot of files/drivers from the CD. As soon as it finishes this and tries to start the Windows kernel, it crashes with a blue screen. STOP 0x0000007F error. If I use the same patched ISO to install it in 86Box, it works correctly. Also, installing Windows 2000 DOES work on this motherboard. Edited June 20, 20242 yr by Mike C

June 22, 20242 yr UPDATE: I figured it out. The CPU was the issue. It doesn't want to start the kernel on an Intel DX4/100. Codes stamped on this CPU are as follows: A80486DX4100 L5473524 3VOLT SK051 I replaced with an Am486DX4/100 and the XP kernel now boots! Could the intel possibly not have supported CPUID? I thought any DX4 was late enough to support it, but could be mistaken.
