Hee hee.. Nope. Still chewing on it. However, I think I have learned a
few things.
1: (I could be wrong here, but) Don't statically link the PCMCIA-IDE driver
into the kernel. I'm still new to PCMCIA on Linux but apparently Card
Services is required to actually make that device show up as a /dev/hd? node -
and Card Services doesn't like not being able to load the module.
2: LILO on the boot drive doesn't seem to work. I'd love to hear if anyone
has LILO working to boot a 730. But it seems the Thinkpad BIOS support for
PCMCIA drives just doesn't extend into the world of free software for some
reason.
So I'm thinking my next attempts are gonna be along these lines -
super-streamlined kernel, everything in modules except for the vitals - initrd
and the filesystems. initrd image will run card services (which will
hopefully find the drive, install the module, and allow me to boot) - from
there, a regular root volume setup.
For a bootloader, one version of DOS or another calling straight into
loadlin. Since on startup the kernel image and initrd image will have to be
in memory at the same time keeping it all small enough for the 8MB is key.
I'd love to hear if anybody has any useful input on this - and also whether
BSD might be better equipped to run on this neat little machine.
