If you boot using acpi=off you can use the Linux Firmware Developers Kit ( http://linuxfirmwarekit.org/ ) to debug ACPI issues. Then you'll have lspci available to check against what the tables are saying.

I couldn't use the factory DSDT for my mainboard because so many of the initialization values were different when booted with Coreboot. > I wanted to discard the linux problem so far and concentrate on Windows XP > install.

Linux is much more forgiving. I personally wouldn't try Windows without Linux working. There's much more debugging information available with Linux. > This error indeed point to "Inaccessible Boot Device" and the second > argument 0xc0000043 points to "Status Object Name Not Found" > > This post is quite old and nothing have been answered to it since July 2008. > You probably been able to fix that issue.

I haven't gotten that quite right yet. Thanks, Myles -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
