OK I got my parts from googlegear yesterday: Celeron 1.1 and SOYO slotkit. I followed the instructions and installed them in my computer. The initial setting I used were:
CPU Operating Speed: user define
Turbo frequency: disabled
Ext. Clock (PCI): 100
Multiplier Factor: 11
SEL100/66# Signal: high
AGPCLK/CPUCLK: 1/1
L2 Cache Latency: Default
Speed Error Hold: enabled
CPU Power Supply: 1.75
But when I saved and rebooted, the computer halted after detecting the CDROM. So I turned the speed error hold off. Then everything booted fine with 1100 MHZ!
When windows finished booting. I checked the reported CPU speed was 1068 MHZ. I didn't know exactly what it should be, but it seemed close enough for me. I then started to play a game to test out the system. Within a minute, and the computer locked up and the screen went black. I Hard rebooted and set the AGPCLK/CPUCLK to 2/3. Then played the game again, and it didn't crash for an hour. So I rebooted once more, and set the Turbo frequency to enable. The computer still booted at 1100 MHZ, but windows reported the CPU speed to be 1118MHz! So now I am happy! The old bh6 lives on!
Hope some people may find my experience helpful in upgrading their own system.
Feel the Joy!
