Error Loading Operating System

Solution 2:

Another cause for this problem may be that an ATA-66/100/133 drive is attached with an 40 pin cable instead of an 80 pin cable. I can’t verify this but consider it as enitrely possible for Microsoft to choke on that so I thought I’d put it up here.


Update I:

On two of my test systems I was able to set the BIOS setting back to “Auto” after the installation of XP had finished. Your mileage may vary.

Update II:

The system I had this problem with is a Pentium-IV 3,06 GHz with an Award BIOS 6.0 with any part of it hardly being any older than 18 months.

Update III:

As I just found out some genius introduced a new way of setting the access mode in some BIOSes. Instead of allowing to set the access mode in the “STANDARD CMOS CONFIGURATION” screen, you have to use “IDE HDD AUTO DETECTION” instead. When the BIOS reports your drive there, you *don’t* press “Y” to accept but instead press “N”. You should then be able to chose whether to use “LBA” (don’t) or “LARGE” (yup) as the access mode for the particular drive.

    This definitely doesn’t sound like a problem related to the hard drive but rather seems to be either a driver or a bad memory chip problem.
