Just a request to include the ACARD SCSI driver on the LiveCD - I was quite surprised to boot the LiveCD just now and be told it couldn't find a root device! It's part of the mainline kernel, so is there any real reason to have it omitted? Reproducible: Always Steps to Reproduce:
CONFIG_SCSI_ACARD=m It is included. Did you try to modprobe acard when it dropped you to a shell? If it doesn't auto-load via genkernel, it would be because it causes lockups on machines that do not have the card. Simply loading the module manually and then pointing to the boot device, as instructed by the Install CD itself, is enough to boot.
The module I use is called atp870u, not acard, but when I was dropped to the minimal ash shell during boot, I couldn't see either in /lib/modules/linux-2.6. xx-gentoo-rx/kernel/drivers/scsi/ After attaching an IDE CD drive to the system and booting the LiveCD from that, there seemed to be more modules in /lib/modules/X/kernel/drivers/scsi/ including atp870u. I stand confused!
