Ok, so... can we change:
target/device/net5501/target_skeleton/boot/grub/grub.conf
to include:
title AstLinux (Boot from CF - Use USB KeyDisk & broken root IDE emulation)
root (hd0,0)
kernel /boot/bzImage root=/dev/hdb1 console=ttyS0,19200n8
astlinux=net5501 astkd=/dev/sda1 ide=nodma
as a third choice?
where does target/device/net5501/target_skeleton get unpacked from anyway?
