Here I made a stupid mistake, didn't notice it under the pcmcia menus so I searched for PCMCIA, so I missed it, as it's under the IDE menu with the name CONFIG_BLK_DEV_IDECS so my bad there :( I recompiled my FAI installer kernel with that on and it Just Worked :) So that was the faulty point. >Either way, the particular flash card you are using needs to be >recognized by the kernel driver in order for things to work >automagically.

This is not handleable by udev, to have the rules there for creating nodes? Or do I need to patch the drivers to have udev play along? Documentation/pcmcia/devicetable.txt isn't really clear either on where I'm supposed to put those crc32 hashes... Anyway, seems my card is supported anyway but it would be interesting to know this stuff :> >When using LB there are at least two tricky problems with what you >(and I) want to accomplish: >1.

I'm actually thinking about skipping FILO if possible, so I have the kernel and and a small-enough initrd as the payload. Have to admit I haven't really checked sizes yet, but the via spec said the bios is 2/4Mbit, so 4Mbit should fit pretty much... Any thoughts on this? It is still always sad when hardware doesn't really work or is very hard to fix :/ >2.

This may turn out to be a severe problem. Anyway, my roadmap is pretty much that next up I'll set up a local debian repository so I can install a kernel. Then I'll have FAI install on the cf. After that (because seems it's now supported) I'll test boot with the factory bios and grub. .. And then there will be linuxbios, finally :) >1 needs further investigation.
