i had a dell inspiron 1100 with celeron 2.3 b4 and i replace the cpu with a p4m 1.6. testing show it run at 1.2G and it work fine most of the time(crush IE from time to time but mozella seems ok). lately i try to install a external security key(usb-like). but it fail with suggestion 'trying on a more stable system). so i put the old celeron 2.3 cpu back but fail to boot with no display at all.
according to dell i have to make a bootable bios upgrade cd and boot with the cd and then flush the bios/cmos to get it to work with old cpu.
anyone has any idea?
