More info? What information is not passed?
Well, usually the BIOS enables access to the IDE bus, but not with me. But
how does WinNT work on the T20 then..? Also lspci does not show any device
identifiers -- just loads of cryptic numbers..
mknod /dev/root b "$ROOTMAJ" "$ROOTMIN"
This also did not help -- 'cat: /dev/root: No such device or address'.
Major/minor is 4/0, as recommended in the kernel docs for /dev/root.
So where can I find my flash memory..? Again, with GRUB I just had to
specify the device address (0x80) and the kernel/initrd positions in
sector syntax, which works fine. Maybe I can do the same in Linux with my
ext2 partition, to specify the start and end sectors ('Specify drives
manually..'). But where to start?
Here's some other info (typos may be included):

8 sd
44 ftl
65 sd
66 sd
67 sd

69 sd
70 sd
71 sd
93 nftl
128 sd <-- Is this my 0x80 device..?
129 sd <-- ..then this would be my 1st part.. [1]
130 sd
131 sd
132 sd
133 sd
134 sd
135 sd
[1] ..but how to access that block device then? What major/minor combi is
needed here..?
