Hey.
So I am trying to install Windows XP on a T480 with has an Intel i5-8350u CPU.
I know laptops are not recommend to do so, but I still want to continue. So basically what the setup fails is the blue screen with the ACPI compliant error (0x000000A5) BSOD.
Is there any workaround to resolve this?
Am I missing the AHCI-SATA drivers? Not sure which one should I integrate using the nLite here? Can someone tell me which should be the correct version?
Thanks a ton.
@sqpp
BSOD A5 is an ACPI error
If you’re using XP 32bit we have a patched acpi.sys driver
Windows XP SP3 32bit and modern PC parts (139)
If you’re using XP 64bit we are working on it
Unfortunately, I have 8GB of RAM so not sure if that’s gonna fit my needs.
How about the 32 Bit with the windows xp pae patch? That should work?
Also, how should I include the acpi.sys in case with nLite?
@sqpp
it depends on what you want to do with XP
pae patch will let an individual 32bit program use up to 4GB each
but pae patch wont allow you to run 64bit programs - you need XP x64 for that
Really just for testing purposes, not really for daily use, but I have also found a 64 bit acpi.sys in that forum. In case I want to risk it and check if it’s working how to include this so installation can go ahead?
@sqpp
there is a few things you need to do to integrate the 64bit acpi.sys driver
grab cabpack 1.4 -
https://www.techspot.com/downloads/7104-cabpack.html
in cabpack 1.4 point it towards acpi.sys
for example
Source Dir or File:
C:\ACPIPATCH\ACPI.SYS
Destination Dir:
C:\ACPIPATCH<br />
CabinetNameTemplate:
ACPI.SY_
once you have ACPI.SY_ you copy it into your XP I386 folder and replace it
Secondly, there is usually a backup copy of acpi.sys in SP2.CAB SP3.CAB and/or DRIVER.CAB (i forget which) that will need replacing
So for example, use 7zip to extract SP3.CAB to a folder - C:\ACPIPATCH\SP3
copy C:\ACPIPATCH\ACPI.SYS into C:\ACPIPATCH\SP3 and overwrite it
then with cabpack 1.4
Source Dir or File:
C:\ACPIPATCH\SP3
Destination Dir:
C:\ACPIPATCH<br />
CabinetNameTemplate:
SP3.CAB
now that you have ACPI.SY_ and SP3.CAB, copy them to your XP I386 folder and overwrite.
then rebuild ISO with nlite.
Thanks a ton 
Yes, realized 
I was searching a bit. but found. Also, it was the DRIVER.cab that included the acpi.sys file.
@infuscomus Regarding the SATA drivers, do you have any clue which one to use? The universal I guess?!
I don’t think it’s gonna work, seems to fail everytime (but not the same message though like earlier)
Update, now it’s not had any error, but failed again with the same BSOD code
Yes, that’s the one I actually used, but no. It fails with the same code.
