If this is better asked on gentoo-amd64, please let me know. I am new to Gentoo, but have used GNU/Linux as the only operating system whenever I have a choice (on workstations and servers) since early 2001. Even then, this has me really stumped. Maybe someone can offer some insight...
Setup: AMD64 system built around a Canyon Tech CN-8N2ALSR4 motherboard
(Nvidia NF3 chipset). Two PATA IDE channels on board and in use: on
ide0, the system hard disk and a smaller one [which fails to be
detected, but that is not a big issue], both using Cable Select; on
ide1, a DVD+-R/RW drive as master (hdc) and a hard disk as slave
(hdd), the latter used for data storage. System installed as stage3
followed by lots of emerges, including `emerge --update system' about
12 hours ago.
The two disks that really matter show up just fine, and the one that
doesn't (an old 20 GB one) doesn't show up in the BIOS either. The DVD
drive, however, shows up during the POST but Linux won't recognize
that it's there. `dmesg' says, in part:

ide2 and ide3 would presumably be the two S-ATA connectors on the
motherboard (that's what they show up as in the BIOS) but those are
not relevant right now. I think the "wait for ready failed before
probe" on ide1 has something to do with this, but tried popping in a
CD which changed nothing. My uname -a output is:

The kernel command line is (and yes I know that my partitioning is
somewhat unusual: /boot is on hda5 and / on hda6):
# grep ^kernel /boot/grub/menu.lst
kernel /kernel-2.6.11-gentoo-r7 root=/dev/ram0 real_root=/dev/hda6
init=/linuxrc vga=0x318 video=vesafb:mtrr
# dmesg | grep command
Kernel command line: root=/dev/ram0 real_root=/dev/hda6 init=/linuxrc
vga=0x318 video=vesafb:mtrr pci=routeirq console=tty0
#
There are other oddities in the dmesg output too, like ALSA claiming
to not having found any sound card but sound working perfectly once I
turn up the volume a bit. I will deal with that later, however.
(Besides, it's more cosmetic than a real problem.)
The DVD drive worked fine during the installation of the system (using
the 2005.0 universal CD), which leads me to believe it is something I
have done - probably a kernel configuration option, maybe something
else - but I can't figure out what it might be. Maybe the cable bits
not being set correctly has something to do with this? If so, any
suggestions as to what BIOS settings to tweak would be appreciated - I
didn't see anything that looked relevant. I would really rather not
have to invest in a new CD/DVD combo writer.
If anyone can point me in the appropriate direction (even if it's just
a pointer to a section I overlooked in the Gentoo Handbook or kernel
documentation), I would be very grateful.
