Yep, but it seems that's what the BIOS does. I verified with superiotool (I added W83627EHG support, patch pending). > You should check and see if the > pcbios sets 24Mhz or 48Mhz.

Ah, yes, CR 0xF0 (page 102 in the datasheet) looks like the register I need. I'll try that. However, the BIOS indeed sets the clock speed to 24MHz (CR 0x24, bit 6 was set to zero when I checked). > I suspect that this is the SPD address is different. How do I find out the correct one? i2cdetect/i2cdump? Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org
