[comp.os.minix] Upgrading...disk question

baugh@hal.CSS.GOV (Nam Myoho Renge Kyo) (10/03/89)

Hello,

	First I have Minix 1.1 and am attempting to move to Minix 1.4a.
I have the PC version (not the AT...) but now have an AT class machine
Yea, I got a copy of PC-Minix from a professor, (who was using it to
teach an OS class) then got involved with my masters and one thing lead 
to another, so I'm finally getting to put it all together.  I've got the
1.1 -> 1.2 kit, the 1.2 -> 1.3 kit, and the 1.3 -> 1.4a kits (the last
part of the compiler I have to grab tomorrow...)  While I have one question
still outstanding on the 1.2 kit (mail is in route) I wanted to build
a file system on my 2nd hard disk in my AT to do the upgrading in.  However,
my first disk is a 40mb disk (two partions, so one is C:, the other D:) 
[using the 'Seagate' software and .sys files] and then the 20mb is E: 
Is
	mkfs /dev/hd2 20000 

going to work with the 20mb? Or is it going to look like /dev/hd3.  I'm
assuming that the .sys file makes DOS think the 20mb is E:, and that
minix won't.  However, I'm smart enough to make sure I have a backup of 
C: & D: first!  Next, are the 1.1 drivers under the PC version of Minix 
going to have problems up with the hard-disk given it's using an AT (true
blue IBM) controller??  I am under the impression that at_wini.c vs xt_wini.c 
is going to cause problems (I guess I just re-compile the stuff that uses 
xt_wini?? )  It sure would be nice to be able to just mkfs the drive, copy 
stuff on to it and begin to patch away...  Anybody got some notes on 
this kind of 'porting'??  (notes on problems upgrading from 1.1 to 1.4 would
be nice also, I didn't see anything on NDSUVM1 but I still have to dig 
through the message database....anybody want to help me by directing me to
an appropriate message??,  A guide for building stuff from the net (and
upgrading) would make a pretty helpful monthly-message (& probably help
the S/N ratio ) as long as it was in the descriptive enough, that is,
in the same vein as Glen's minix list.  Maybe somebody has one that they
could post?? 


Well thanks for the time.
