Yes, I see; it's just that you mentioned SRM in your earlier message, so
I decided you were talking about SRM booting as well.

Yes.

Right. That's true when booting via AlphaBIOS. However, SRM doesn't
use linload.exe: it goes straight to MILO. Currently the problem is
that while even in its current state AlphaBIOS lets users select which
MILO to boot, SRM can't do even that. Only one OS per disk, please.
That is, MILO on a CD can't be booted from SRM on arbitrary platforms
unless a middle layer bootloader is provided, similar to linload.exe in
AlphaBIOS boot up process.

Oh, I see...
