You can do both by... 1. Build the modem driver into the kernel. char drivers are linked in before ATA ones, so it will attach first. 2. Using a custom initrd with emergency shell. initrd is loaded by BIOS so no driver is involved. I don't actually know how to do this tho. 3. Put in an extra disk controller and boot from it with both drivers compiled as module. -- tejun
