But of course, moving it to an earlier position is a good idea. However, what I was asking for is how to enable and make use of it, not how to disable it. I think I'll need to look into the i810-tco.c from the kernel sources and try to modify it for SIS630. SG> This will do it in chipinit.inc: SG> #define ACPI_BASE_ADDR 0x5000 Speaking of ACPI... I can't get it working with LinuxBIOS. ospm_*.o modules won't load and the kernel complains on being unable to read ACPI tables.

What I would really like to see somewhere in the LinuxBIOS code is the options to disable SiS630 embedded modem and audio controllers. I browser through the datasheet and didn't find how to disable them. I probably should re-read it, but if anyone knows the way already, I'd appreciate showing it to me. >> I'm having problems with the serial console when booting LinuxBIOS on >> a pcchips m787cl+ motherboard.

It was a problem of an old init, as Ron suggested. I ugraded init and the problem is gone.
