So if you add DOS to the floppy disk it will run in less RAM? Will your
download contain both syslinux and loadlin, and we remove one or the other
depending how we use it?
BL3 works in 3MB RAM but only if run from hard disk. You can hit Ctrl-C
instead of loading the second disk (you lose X and modules, I think).
How much of the 3MB is left after booting your disk, to run programs in?
David Moberg put together a 1-floppy BL-based linux with kernel 2.4.31 and
usb-storage and mouse driver, useful for copying files from a usb-storage
digital camera and viewing with zgv. I forget how much RAM it needs. I
put a small BL3 onto it and can boot with floppy then chroot to it to view
and edit images. Would a larger kernel also fit into your SAMEL?

With telnetd. Will it have e2fsck (not in my asmutils), mke2fs?
You could probably shrink the BL3 kernel some more.

Interesting story. What is a Spectrum? I STILL use linux with TTL and/or
mono VGA, and 360K floppy drive.
