For those of you that didn't see the previous thread, I have an HP Pavilion 8370 although there are many Pavilions that have the ASUS P2B98-XV MOBO installed. If you have an on board ATI Rage Pro then you probably have this MOBO.

Well HP puts the worst BIOS known to mankind...a Phoenix BIOS with absolutely NO settings that you can modify other than the typical stuff. Nothing for us techies.

So, I go to ASUS's website and they have a BIOS for the ASUS P2B. It's an Award BIOS and it has all of those techie settings. So, I flashed my BIOS using UNIFlash, only one that will work unless you have an EPROM burner. You can get it here-


So I flashed it and the Setup Utility was there, only it wouldn't get past the darned Setup Utility. It kept going into it with a flashing message at the top that read-

'System not shut down properly or CMOS Checksum error. Check CPU Core Frequency'

Also, it would display 'Pentium II 175MHz' as the detected processor even though I have a PII 350.

That's all it would do, however I have 'dog with a bone' syndrome and I was determined to see if I could get this working.

Well, I fiddled and fiddled changing the entries for CPU Internal Speed, CPU Multiplier, and BUS Speed until finally, magically, it made it past the Setup Utility. Here's what I found out.

You must set the CPU Internal Core Speed to 'Manual' and the Multiplier to '2.0'. Yes I know, I have a PII 350 installed but according to ASUS's manual on the P2B98-XV, the CPU Internal Core Speed setting is 'Reserved for future use and currently disabled' which I believe means that if you try to set it to what it should be, it'll detect a mismatch.

You can go ahead and set your BUS speed to 100MHz(They have it set for 50MHZ) and VOILA! Reboot and it now reads-

'Pentium II 350Mhz'

It does all of its error checking and then proceeds to load Windows. :)

The only thing that was weird(not so weird looking back) is that since this is a new BIOS and I had PNP set to off, all of my drivers were re-installed upon entering Windows. Luckily there were no problems and after rebooting a second time, everything was perfect.

So...hopefully this will help all of those who have a Pavilion with an ASUS P2B98-XV installed and would like to get a BIOS that has all of those settings to play with AND get updates as the last update from HP was in '98. The one from ASUS is from this year.

Thank you Henry for all your help and Good Luck to you all on your BIOS problems. Once in a while, things actually do work out.
