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..

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):

[1] ..but how to access that block device then? What major/minor combi is needed here..?

Hope this helps.. somehow.
