Ubuntu Linux 7.10 RC amd64
ASUS M2A-VM mainboard
Configured in PATA emulation mode so that Windows Vista works. (I'm not
sure what they called it on the BIOS settings, but it's the opposite of
AHCI mode. In Windows they show up under a generic ATA controller.)
Mainboard:
SATA4 (empty)
SATA2 Seagate ST380013AS 80 GB HD
SATA3 Seagate ST3250820AS 250 GB HD
SATA1 Seagate ST380817AS 80 GB HD
PATA1 LiteOn DVD-RW
(The physical ordering is weird! The front two connectors are red, the
back two are black. I assume the ordering is due to RAID. There is
only one PATA channel. I have no PATA hard drives, only the DVD drive.)
BIOS:
HDD1 Seagate ST380817AS 80 GB HD
HDD2 Seagate ST380013AS 80 GB HD
HDD3 Seagate ST3250820AS 250 GB HD
HDD4 None
Boot order is:
CD
HDD1
HDD2
etc.
Pretty sure that was the case during both installation and normal
operation. I changed it once to (CD, HDD2, HDD1) after Ubuntu wouldn't
boot. Doing this seemed to change Linux's device names, and it couldn't
find the root device. I changed it back. I don't think this has any
permanent effect.
Windows:
SCSI 0,0,0 Seagate ST380817AS 80 GB HD
SCSI 0,1,0 Seagate ST380817AS 80 GB HD
SCSI 1,0,0 Seagate ST3250820AS 250 GB HD
device.map after install:
(hd0) /dev/sda
(hd1) /dev/sdb
(hd2) /dev/sdc
corrected device.map:
(hd0) /dev/sda
(hd1) /dev/sdc
(hd2) /dev/sdb
This looks weird, but it's right since Linux detects HDD2 (what Grub
calls hd1) as /dev/sdc.
$ ls -l /dev/disk/by-id | awk '{ print $8, $9, $10 }'

Let me know if there's any other info I can provide.
