hi,

I have:
http://www.shopping.hp.com/shopping/data_sheet/rk548aa.html

I've downloaded latest bios (v.5.21) that HP is uploading and after that I can't set my defalut graphic source as PCI-E because I have no option to choose it (have only PCI and Onboard).
I've managed to download a previous version I had (5.03), but during the installation there is an error saying:

"incorrect BIOS for your sytem (253).
Please download patch again. If error continues contact support"

I am 100% sure about the file because in installsheild wizard there is everything exactly like it should be (for win vista 32bit, p5lp-le etc. )


could anybody help me?

Do NOT try to install the old BIOS; download a FRESH copy of the 5.21 BIOS, and flash the BIOS again. I think the BIOS you originally used might have been corrupted... Here's the link:

Follow the instructions on that page EXACTLY when you reflash the BIOS, and let us know what happens...

Good luck; let us know how this turns out...
