mb=Biostar p4m900 Micro 775
chipsets= northbridge - p4m900 ; southbridge - vt8237a (both VIA)
I upgraded the older Celeron D processor with a (fully supported by mobo) E6700 Coe 2 Duo.
First I followed all instructions to flash newest bios from MB manufacturer.
Then I installed new cpu. The new CPU was shown in POST. Great. Booted up Windows and the CPU was not seen at the correct speed. Did a reboot and still no go. Did some research and decided to reset CMOS and try again.
I reset the cmos (jumpers 2 &3) closed.
After reboot I see the correct CPU at the correct speed settings.
At the POST,
Correct bios version displayed.
(correct displays for memory, drives, etc.)
Floppy disk fail! [40] (because the bios was reset to defaults which enabled floppy and I don't have one.)
CMOS defaults loaded.
Warning! CPU has been changed.
Please renter CPU settings in the CMOS setup and remember to save before quit!
Press F8 to enable system configuration.
Press F9 to choose drive to boot after POST
Press F1 to continue / Press Del to enter setup
In a nutshell, I can get the bios and OS to boot (WinXP-sp3-current updates installed) to see this new cpu at it's correct speed.
But only by pressing F1 continue. If I press DEL so I can disable the floppy or to set the correct date (it's off by years) , or ANYTHING, and then Save and EXIT, then upon reboot the sytem displays the incorrect CPU speed and the FSB is also reset too low. Then I'm back to resetting CMOS again. Round and round.
NOTHING I tried to do in bios settings allowed me to change the FSB or even the CPU speed or multiplier. They are either greyed out or don't exist as options. I know I have the latest bios for this mobo. I'm stuck with the defaults; floppy stop error, messed up date, no PNPlay, can't change boot sequence, etc.
I'm stumped.
