XP will not install without disabling acpi

The acpi settings cannot be disabled in the bios and pressing f5 and choosing the type of pc has not helped the disc has been used before sucessfully on this machine but was requiring a reinstall because the registry was corrupted and i didn't have my system disk on hand. this problem started after the purchase of ram for this machine which is an acer power sx series
600mhz pIII
10gb H.D
acer cd rom

from memory it is using a stealth bios at the moment im able to run 98 on it. but of course would like be be running xp any help would be greatly appreciated

 

XP is more sensitive to impending hardware failure.

Also, sometimes XP has problems detecting whether or not to install ACPI Hals. I've seen people do upgrades, and it not install ACPI, and I've seen those same people turn around and do clean installs and have trouble because XP all of a sudden is trying to install an ACPI Hal. You've got a fairly old system there, the chances of it supporting ACPI 1.1 (which XP uses) properly are slim anyway. It would probably be more stable just to leave it off, using F5, as you did before.

Of course, one of the very common reasons for registry failures is from ram corruption. Being that you just added ram, and ran into a problem, and now XP will not install normally for you...

Did you try removing the ram and trying again?

 

yes it did not help there either but the thing was was that the machine had run xp fine before that and i had disable acpi then to install it after having device not ready issues which that resolved

 

Had this problem over the weekend.. this did it..
"To resolve this behavior, contact the manufacturer of your computer to obtain a BIOS that is fully ACPI compliant.

To work around this behavior, manually install the Standard PC hardware abstraction layer (HAL):
1. Restart the computer to restart Setup.
2. When Setup starts again, press F7 (not F6) when you see the "Press F6 if you need to install a third-party SCSI or RAID driver" screen.

Windows automatically disables the installation of the ACPI HAL and installs the Standard PC HAL. "

 

We have already been discussing it. F5 does the same thing, but its interactive.
