VICTORY!
I was playing around again (and again) and decided to give the ide disk a
low level format one more chance. I changed the IDE cable and let it
format for a good 3 hours and came back into the room, to be greeted by
the message:
"Next, run FDISK and FORMAT"
Press Ctrl+Alt+Del
I fdisked to 76mb, formatted and watched Dos 6.0 spin into life!
The problem? I guess the system didn't like the IDE cable (although it
works fine in other PCs). Swapping it out seemed to do the trick! <me
thumps head on desk x1000).
Just want to say a huge thanks to everyone on the list, especially Jim, Bob
and Rick for sticking with me and giving me different angles to try. Truly
a great usenet spirit is still alive in this group today! The posts may be
infrequent, but I know it's watched by a core of devoted experts!
Cheers again,
Ali

Yeah, but I'm starting to wonder what "Disk table is scratched" really
means. This obviously isn't a DOS error message. And I'm wondering if
this is some kind of fault error about the EEPROM - whether or not the
drive parameters table is "scratched" - as in has been trashed in some
way - to make it a "bad thing" to install any drive with this
controller.
Yeah, that's been a worry of mine also, sitting in the back of my head.
The card does indeed have a BIOS and an EEPROM. Bios is at C800h, EEPROM
is at 27256 - 0000-1FFFh.
How's this for another curveball - The drives I've been setting this up
with are all not old enough to have an actual 'type'. In the case of the
80mb one, it was very close to a type 25 in specs (but the pentium picked
it up with slightly different chs values), so I tried forcing it to be
type 25 in the bios of the pentium, fdisking and formatting. This seems
to work just fine on the pentium.
Could the problem with the JUKO card be that it *requires* a drive of
the 'type 1-46' vintage. There is no option to use a type '47'
user-define as Jim suggested, if I try typing it in, it asks to reboot
the system, just like it does when i say no to pre-format.
Can you run MSD.EXE on this thing? There are memory block display and
memory browser options in MSD that might reveal something about other
built in messages on the BIOS on this controller card. If this thing
allows you to store at least one drive table parameter you can enter
yourself I'm kind of assuming it has a BIOS and an EEPROM on the card. I
suspect the fault is with the EEPROM if you are manually entering the
drive parameters.
I don't have MSD unfortunately, I do have debug, that's all, and I can
see the messages given out by the controller from C800 onward. I wish i
could access the EEPROM though, that would be the handiest thing - then I
could perhaps just enter the value 25 into the table there and see what
happens.
EEPROMs do fail. I have an old Reveal sound card that stored
configuration info on an EEPROM. When the EEPROM crapped out it stored
all manner of junk, including adding extra phantom parallel ports to my
system.
I do hope that's not the case. If it is, then this is a very expensive
painful exercise indeed.
P.S. It's kind of annoying re: how many sites there are out there that
have the jumper setting info for this card, but squat about either a
manual or any practical "how to" setup information.
Absolutely! I've been searching and re-googling for weeks on this now to
no avail.
Cheers,
Ali
