I'm sitting here thinking about how we might make the CD even more
useful in the future, and in addition to the usual creature comforts
(which I'm also working on) I was wondering about the following
pie-in-the-sky ideas:
1. Boot direct from CD. It's my understanding that certain SCSI
adapters support this - any clues as to which ones do and how
you might go about making them do it? Naturally, we'd also have
to figure out some way of getting boot blocks onto a CD.
2. Take advantage of Win95's `autolaunch' on CD insertion to do
something clever. Not exactly sure WHAT yet, but it's an idea.
I was also talking with Poul-H and Joerg about the idea of getting
access to additional command-line args, and how hard that would be.
In particular, I'd like to be able to do something like:
boot -c aha0=0x330,10;ed0=0x300,10,0xd000
And be able to get at the argv[3] from userconfig, treating this as a
`run these commands and leave' sort of op. This would be especially
useful from boot-from-{DOS,Windows} mode since you could have a nice
little Windows interface for `personalizing' the kernel before booting
it and you'd never have to mess with -c directly at all.
Thoughts?
