Damnation

@Dietmar The one I linked does, maybe try that?

@Dietmar Does IDE work at least?

@Dietmar I'm not sure how to tell if it has a boot ROM or not.

@Dietmar These VIA chipset PCI cards have drivers going back to win3.1. https://www.ebay.com/itm/195952338235

Dietmar knows how to switch properly from Standard PC to ACPI. @Dietmar can you show him how you did this?

@Cixert It's not that simple to switch over to ACPI with an existing XP install. @Dietmar knows how to do it properly and can help.

@Cixert You may as well try it and see if it works for you. What ACPI BSOD are you getting btw? have you got a screenshot.

@Cixert Have you tried the updated community made 7777 acpi.sys?

@Cixert Has the boot order changed in the BIOS since the update?

It has to be 256 colors I think.

@Cixert Is your boot drive visible to the BIOS after you update?

@Dietmar I recall you saying you had encountered this black screen issue before? did you manage to fix it?

@gordo999 You can make a new thread for it if you want. I'm not sure what's going on with your XP, maybe @Dietmar knows something that might help.

@66cats This is all the acpi.sys files as far as i know, including the newest acpi.sys I have. https://ufile.io/xl07mr8a @Dietmar might have a newer one though.

@gordo999 Bricked XP install probably.

Oh hey, the forums are back!

@ackmangogo That's good to hear!

@Zorba the Geek Try Relyze disassembler, or ghidra disassembler, and see if what they output is suitable. Both are free.

@Mov AX, 0xDEAD Ahh, whoops! Thanks for that.

@Mov AX, 0xDEAD I just tried to apply your most recent .patch file for a build. Did I do it wrong somehow?

@Dietmar Can you run a debug on storport 8.0 beta 8102 to find the cause of this storport 7E BSOD? (remember to restore original XP SP3 HAL and acpi.sys before running debug this) dietmar_storport_8102_7e.7z

@SFMG Sorry to hear that. You could try looking around at one of those PC recycling places and see if you can pick up a GPU for free.

@SFMG I'm not sure what your needs are, you may as well try out the driver and see if it works for you.

@SFMG If you're stuck with the RX580 then you'll have to settle for a generic 2D driver in XP. bearwindows.zcm.com.au/vbempk.zip

@SFMG I'd say your best option would be to get a cheap Nvidia GT 710 or 730 and run it along side your RX580 in a lower PCIE slot. Nvidia kept XP support up to GTX 980 whereas AMD dropped support around the R7 270.
