Ah so that is why it works for me but not for him, since I always customize my CMOS options :D > No idea why combined mode is the default, it's only useful for OSes from > the '90s.

AHCI is faster and better as it supports NCQ, TRIM etc. Conga-rats petey now you can fix it easy! just enable cmos settings in menuconfig then go to the kgpe-d16 coreboot board directory and change cmos.default, recompile/flash then reset your CMOS - OR if you already have use cmos enabled you can simply change it via the cmos tool with the required iomem=relaxed in the kernel command line. I would also lower the log/debug level via menuconfig to speed boot times and maybe change some other things in cmos.default like me I have experimental_memory_speed_boost enabled, my 1394 controller set to disabled and SATA ALPM to enabled. -- coreboot mailing list: [email protected] https://mail.coreboot.org/mailman/listinfo/coreboot
