bsod when downgrading

[siscokid1]

Greetings,

Trying to downgrade daughters pc from Vista to XP, receive BSOD saying either update BIOS etc or disable shadowing or caching

Not sure where shadowing or caching is.

attempting to update BIos, any help appreciated.

It's also a setting in the bios. What is the stop code?

As mentioned, it would help knowing what BSOD code you are receiving...

and belay updating the BIOS, any PC that runs VISTA is capable of running XP (less finicky)...

it is STOP: 0x0000007E pci.sys

Thanks.

There are numerous individual causes for this problem, including hardware incompatibility, a faulty device driver or system service, or some software issues.

source: Aumha.org

e.g.:

You receive a stop error 0x7E in Pci.sys

I have a feeling that XP is trying to use a driver that was not meant for a particular hardware device...


I would suggest, that you 1.) Slipstream SP3 and 2.) add all hardware drivers for that particular PC...

I can only recommend the following program for the integration of SP3 and drivers...

nLite

Yeah - those 7E BSODs are a real pain sometimes.

I'd check the memory just for kicks, but it IS likely a driver.

If XP was already 100% loaded, you could boot to a bootable CD and copy a known good PCI.SYS to the failing system and see if that made a difference.

Failing that, you have to start from scratch with a known good CD of XP with SP3 as mentioned.

ok....I've never slipstreamed before, but I'll try....gtg drivers from Compaq .....let u know

Thanks

I tried making a slipstream 2 no avail :-(......it doesn't even recognize the disk ....it is an ISO tho..I knew I h8 compaqs 4 a reason

 

[rclarke250]

There are a lot of different directions on how to slipstream, I like the directions on this site.

Easy to follow, and all of the tools are free to try or use.

What do you mean it's an iso? if you look at the cd in explorer? if it is an iso it needs to be burned as an image, or it won't work.

If you use a SATA hard disk it could be something to do with how your SATA controller is configured in the BIOS. If I remember correctly AHCI mode is only compatible with Vista or later - for XP you need it set to IDE mode (it may be labelled as something else such as legacy or PATA mode).

If that's the problem then you won't need to slipstream SP3, you can just use your existing CD.

There is Pata controller and sata1 controller, which the only option is enabled/disabled, I do not see an option for stopping caching or shadowing

 

[siscokid1]

..yeahhh..that didn't work..tried making disk, did not boot, came up to d prompt.....do not see AHCI in Bios

 

[siscokid1]

well...I'm loading Winders 7 (eval) on the sucka now, so I think this will be much better

Thanks for your help

@Nelveticus - AHCI will work also for XP, though it will not speed up anything, and you need a driver floppy (or integrated) for it to work...

@siscokid1 - with 7, you will not be disappointed, it is just as fast or even faster than XP, good choice...

though Slipstreaming is straight forward, there is an option in nLite to create an ISO file, which you then burn using an imagae burning software of your choice...

Good luck and have fun with 7...
