You may or may not see this on XP. But when you see it you want to get ready to re-install the OS from the machine's maker. If the maker does not supply a XP ready BIOS then you don't run XP.
Blue screen--> Error says;
Bios in system is not fully ACPI compliant. please contat your system vendor or visit www.harware-update.com (link is non existent) for updates BIOS. If you are unable to get an updated BIOS or the latest BIOS supplied by your vendor is not ACPI ompliant you can turn off the ACPI mode during text mode setup.
Press F7 when prompted to install storage drivers, system will notify you that F7 was pressed and it will silently disable API and allow installation?
(I tried the f7 and not sure about this, I didnt get no f7 key was pressed message)
***Notes
Been getting this message after windows receives updates lately. did system restore through safe mode, thought it corrected the problem for weeks and it happened several times after each windows update soon again. Now I cant even do a start in safe mode it just goes straight to the blue screen.
I tried re-installing windows from the pause break, f11/ctl keys down and reinstalled the DELL XP media from hard drive whih says it was suessful, but I still get the same error. Reason I reinstalled was because DELL Tech told me to so. Side note- my dell warranty is expired and they wont help me unless i pay them. I begged them to at least help me and they told me about the reinstallation mode from f11 and that was it.
I did a little research and it sems to be with the system going into hybernation mode or sleep mode which may cause the system to get an eror while idle and while dowmloading windows updates?? which may have to work with ACPI from what I can tell. The question I want to know is, how do I get my DELL Dimension E521 to start bak up in safe mode or normal and then how do i turn off the ACPI or take windows out of hibernation once I get it up.
Thanks,
Ryan
