Okay. Here's the deal:
I have a secondary machine (i386-33/64k ISA) which I just made out of spare
parts. I think I hosed the old 40MB MFM hard drive by putting in the wrong
Question 1: Can you ruin a disk by doing that?
It low-leveled just fine after I put in the right parameters, and then the
media analysis and high-level worked, but the next time I cold-booted it
died and won't read the disk.
Question 2: Why?
So I'm thinking that the best way to do things now is to get two ethernet
cards, and hook the 386 machine as a ms-dos machine, to talk to the faster
i486DX/2-66 running NetBSD. I am thinking that the netbsd machine can
NFS export it's ms-dos partition (which is already mounted in /mnt/dos)
and the other machine can use some kind of PC-NFS to run on it.
Question 3: If so, what MSDOS software can I use?
And I'd like to boot using bootp, if possible, rather than a slow floppy.
Question 4: This is possible using what cards? I know SMC elite... any
others? Anything special I have to do?
Question 5: Finally, given this setup, what cards would you choose,
and what topology or wiring? BNC seems the most easily extensible;
with TP I'd have to get a concentrator (or so I believe) when I go to
3 peer units. Any other options? Do they have fiber network cards in
the low price range (yet)?
Question 6: Is getting a VLB or EISA network card on the NetBSD/i486
machine worth it, if I still have an ISA hd controller? (I assume not)
Question 7: I'm looking at getting a new hd controller soon; I have
an AHA-1542B now. Should I go with the bustek EISA controller, or
some VLB controller? Real experience valued here. I hear that some
vlb disk controllers can significantly slow down the CPU. rumor?
PS: The attached disk is a year-old Microp 2210s. No other drives yet.
Another factor may be that NetBSD-curr doesn't have EISA support back
in yet, and I've already recompiled since then (dumb move)!?!
Thanks for wading through all this!
