13 I'm not sure what you're asking. Can you elaborate as to what you're
14 asking?

16 As I'm in an office, there is no concrete nearby for anything to be in.
17 I see my monitor, I hear my mp3's playing, and I smell my peppermint
18 tea. But I'm pretty sure that's not what you're asking me. :-P

20 If you're asking what, specifically, I mean by "it starts", my previous
21 posts show how far into the boot process it gets. If I specify by
22 /dev/sda1, eventually it gets to checking that partition for errors, but
23 fails to find the partition. If I specify by LABEL, then it tells me it
24 can't find the label a bit earlier in the boot process, and asks where
25 it can find the root partition. When I tell it /dev/sda1, it continues
26 to boot, only to stop again at fsck'ing the partition. If I put in the
27 root password for maintenance and have a look, there is no /dev/sda or
28 /dev/sda1 in /dev (nor /dev/hd?, nor /dev/sr?). But a "mount" command
29 shows /dev/sda1 mounted at /. And /sys/block has sda and under that,
30 sda1. So it's like it sees it, but then it doesn't.

32 Following the sugegstion from YoYo Siska, I've had a look at the various
33 options I can pass to genkernel (I had followed the handbook previously,
34 and hadn't realized there were options I could pass), and am currently
35 rebuilding it with the following command: "genkernel --install --slowusb
36 --disklabel all". YoYo pointed out that there was a --disklabel option
37 to pass that'd add disk label support to the kernel, and I noticed the
38 --slowusb option that, from my research, sounds like it may have
39 something to do with my problem. Will let you know after I try that
40 what the results are.
