[comp.sys.amiga.tech] ATOnce and MS-DOS partitions

bbs00068@uafcseg.uucp (Joel Kolstad) (12/31/90)

OK... well, I got my ATOnce board, and it's nice.  Too bad it slows the
Amiga side down by a half, though...
 
Anyway, I'm trying to give the MS-DOS side its own partition.  I can do the
"MS-DOS partition in a file" method fine, and it works great, but...
as the documentation says, it's slower than giving ATOnce all of a device
as its partition.
 
So, I backed up by hard drive (Xetec Fasttrak w/Seagate drive), redid the
partitions, formatted them again, and put enough stuff on to get the system
up and running.  BOOT:, DH0:, and DH1: were all there, and Amiga DOS was
happy using them all.  (Boot transfers control to dh0, which uses the fast
file system.  dh1 I intend to turn into c:...)  Boot: got cylinders 1-1,
dh0: got 246-566, and dh1: got 567-811.  And, yes, I did run the "AT
Configure" program to tell it that C:->dh1:.  It seemed happy enough...
 
So... off to booting the MS-DOS 4.00 install program.  It runs... FDISKs
C: (which it properly sees as the 10 megs I had it partitioned too), and
then attempts to format it.  Oops!  "Bad media type or illegal track
0 on drive C: -- format terminated"  Hmm...  Interestingly enough,
though, DOS install keeps on going.  It installs the rest of DOS (after
giving me two "General errors -- retry?"  Retry works fine...), and I 
reboot the system.  MS-DOS shell comes up fine.  Hmm... I think... could
everything be OK?  Well, no, it isn't!
 
Upon getting a DOS prompt, I do a DIR of drive C:  What a mess!  There's
autoexec.bat, config.sys, command.com, and the subdir DOS like there
should be, but also LOTS of illegal filesnames, subdirectories, and other
totally bogus entries.
 
I attempted to just do a DOS format c: /s again after booting off of 
floppies, but I kep on getting the same error message.  I can use C:  
for awhile, but eventually DOS gives me a "Invalid FAT" message --
which is understandable!

Chkdsk /f doesn't help much in that it, too, eventually gives up with an
"Invalid FAT" message.  I can't just DELete or RemoveDir the garbage  
because they almost all contain illegal characters.  Arggh...
 
Tomorrow, I hope to let Norton have a look at it... but I still really
want to know:  HOW DO I PROPERLY FORMAT C:!?!?  I followed the manual
just like it said to, and it's really frustrating that it ALMOST but NOT QUITE
works!!!  Can anyone help me?  I'd appreciate it!
 
Also -- does anyone know if the makers of ATOnce (Vortex, I think... box
isn't here right now) are on the net?  I hadn't planned on giving my Xmas
money to AT&T to pay for overseas calls to Germany. :-)
 
Thanks in advance to those who can help.  Please respond to the 'net or
kolstad@cae.wisc.edu -- NOT this public access account; it'll bounce!
