Hi.

I'm using Lemonzest August 2003 BIOS for PCChips M810L. I'm able to set synchronous host/dram at 100 MHz but at 133MHz everything locks up after I setup the BIOS and reboot the system. Is there a way to fix it up?

Furthermore, does anybody know where to find the SiS 630S or 730S datasheets?

Here are some dumps by WPCREDIT:

Sync disable @ 133 MHz

Register 51h is altered by this option, and when I enter into Windows and play with this register everything locks up.
Looks like this setting is being used for setting the FSB:RAM ratio. It can't be changed on the fly.

What's the processor? Can suggest changing its FSB. Does the motherboard have jumpers to set 133MHz FSB?

My CPU is an Athlon XP 1800+. Mobo is jumperless.
And at BIOS defaults the FSB is 133? And what is the memory's frequency?

Bios defaults at 100. My RAM is PC133 CAS2
