Ok, I just had a look. The console device on the root floppy looks
like:
$ ls -l console
crw-r--r-- 2 root root 4, 0 Mar 7 1999 console
This is normal for a 2.0.x kernel, I believe. Kernel 2.2.x has the
ability to use the serial console as the console by passing
"console=ttyS0" on the boot command line. For this to work, the console
should have major number 5 and minor number 0. I do not believe this
works with 2.0.x. To get a serial console with 2.0.x you need to make
/dev/console a symlink to the appropriate serial device, like:
$ ls -l console
lrwxrwxrwx 1 root root 5 Nov 28 19:37 console -> ttyS0
Since the installation disks use 2.0.x you need the latter approach,
unless you use a different kernel.
root1440.bin is a compressed ext2 filesystem image. In order to mount
it, you need to uncompress it and mount it via loopback. Once you have
it mounted, you can make changes, then unmount it and recompress it. I
have prepared a root1440.bin.serial which should work for 2.0.x
kernels. It is available at:
ftp://physics.clarku.edu/users/gjohnson/root1440.bin.serial
Let me know if it works.
