I recently purchased a new Biostar P4M80/M7a Version 7 with Intel Pentium D 840 and 1 gig of memory.
On first boot entered BIOS settings, reboot, lock at POST screen, and cannot enter BIOS
Could not enter BIOS again
Cleared BIOS picked default settings, reboot lock at POST screen, and cannot enter BIOS
Eventually managed to update to the latest BIOS, reboot lock POST screen, cannot enter BIOS
Repeat all above steps a few times with no success
One time and one time only it reached BOOT to CD, but did nothing
Now I am back to lock at POST screen
I did try to keep it simple, no USB, NO Cd-Rom drive no floppy etc.
