I have a AMD Athlon 2400+, 2.66 processor system with Mb manufacturer : ASUS A7V8X-LA HP/Compaq name: Kelut-GL6E, while installing winxp error msg occures ie: Stop Error Screen instructs me to Disable BIOS Memory Options such as > caching or shadowing. I cannot find, Memory Options, in the BIOS. How to disable caching, shadowing ? pls provide procedure.

You have a board that evidently was built for Compaq (HP). The BIOS would have been cutomized to their specs. If the options exist at all they may be hidden or may be labeled differently. Those terms may refer to video settings. I don't think you should need to change any BIOS settings in order to install WinXP. You should install with minimal hardware connected and/or enabled in the BIOS. Make sure you have all the BIOS settings relating to processor speed and memory timings set to defaults. I don't think a 2400+ runs at 2.66GHz.

All the 2400+ flavors (8 of 'em) run at 2.0Ghz or less. That said, about the only thing to do is go thru each BIOS screen and look for the option to disable/enable BIOS Cache or Shadow, VideoBIOS Cache or Shadow, etc. To echo OtH, those options may not be available and they shouldn't matter anyway. What is the exact model number and/or product number of your machine? It'll be something like a720n for model and PJ509AA for product numbers. Seems like I also recall that most of this era of hp/compaq came with XP Home installed? Skip

You've only got 128 meg of ram in that thing?

Nice catch Dave...I missed that. Skip

So did I. That could be the issue. Can't recall what the minimum memory requirements are. This system may be using at least 8MB for integrated graphics too.
