I'm just sharing some experiences I had with installing Debian on the fit-pc2.
First of all, I never got debian's netinst.iso working with usb boot.
I downloaded the mini.iso from the debian mirrors:ftp://ftp.debian.org/debian/dists/lenny ... nt/images/
netboot - mini.iso
I used UNetbootin to put the iso onto an usb pendrive.
Bootup your fit-pc2 from usb pendrive and get ready to install.
After installation the fit-pc2 has to reboot and is stuck (the famous reboot bug). So do a manual restart, unplug your usb pendrive before boot.
When I booted for the first time, it could not find the root fs. This is because during installation the usb pendrive was sda and the hdd was sdb. You can edit the boot parameters of grub at boot ( by pressing e ).
Change hd1,0 into hd0,0 and sdb1 into sda1.
For the reboot bug, add reboot=b. And to change the resolution by adding vga=794 (see wiki
for more info)
It will look a bit like this:
title Debian GNU/Linux, kernel 2.6.26-2-486 1280x1024
kernel /boot/vmlinuz-2.6.26-2-486 root=/dev/sda1 vga=794 reboot=b ro
Make sure to change your /etc/fstab in case it is wrong.
To solve the devices problem ( sda sdb sdc ... ) you can also use UUID like Ubuntu uses.
Hope these are some good tips. Good luck!
