Hello
I have the following setup:

• PCChips M577 Motherboard
• FSB: 100MHZ
• AMD K6-2+ 550ACZ
• vCore: 2.0
• Clock Multiplier: 6.0
• Frequency: 600Mhz
• ASUS AGP-V3800/32MB Pure
• SoundBlaster 5.1 Live SB0100
• 384MB Ram
• 32GB CF to IDE as the hard drive
• Award BIOS 4.51 PM9900+ITE866-2A5LEH0AC-00 990309J4 From Chkcpu Problem with UDMA, need BIOS fix for Taken TX3 (LGS Prime 3C)

I was looking at fixing the BIOS UDMA issues before I came across Chkcpu’s J4 revision. While I was browsing the BIOS options with modbin, I noticed a section called “Speed Pin Option”. I would love for the turbo button to be more than just a switch that turns the turbo led on and off. I want to run Windows 98 on this machine and then switch over to DOS and turn off the cache with the turbo button if possible to reduce the machines speed. The options under this section of the BIOS appear to give the functionality to do just that.

After an internet search that did not turn up anything helpful and reading the modbin 4.50.58 manual, I am lost. I played around with the settings, but I could not get the switch to do anything more than turn the turbo led on and off. No matter the BIOS setting or which 2 wires of the 3 pin switch connector I placed on the 2 pin motherboard turbo header pins.

At this point I don’t know what I don’t know. Maybe these BIOS settings do not work for this motherboard, I need to switch to a Pentium MMX CPU, I have the settings wrong, or …

Any help would be appreciated.

Thank you
SDW
