*************** Originally posted to misc.forsale.computers **************

(Ok, I'm desperate.  Foolishly I took a plunge with insufficient knowledge.

I recently purchased from the net a used hard drive with controller card, 
which I had hoped to add to my 386 system.  I had naively thought that with
separate controller cards the bus would magically sort out which card was
talking to which hard drive.  (If it could distinguish what each of the other
cards -- video, serial, modem -- was feeding it, it seemed
plausible that it would be able to talk to each controller card without
trouble.)  Of course, it hasn't worked that way, and plugging in both cards
at once leads to trouble, where the best I have managed to accomplish is the
system talking to one drive while ignoring the other.

My system came with a fair amount of documentation for most everything but the
existing controller card and drive.  Also, the 2nd drive I purchased came
with documentation (as advertised) only for the controller card.  I am working
on trying to get information on the original drive from the company that sold
me my system, but don't know if they will be able/willing to provide it.

Both drives work perfectly when the other is unattached, so I think I can
trust the BIOS settings, and the choices of address selection on the control-
ler cards (as well as the person who sold me the drive).

Answers to the following questions would be greatly appreciated:

1) Is it even possible to mate an IDE drive with an MFM drive, providing
   they each have their own controller card, or is this just bad sex?  (I
   have heard different opinions on this one.  The controller cards are, of
   course, of the corresponding MFM/IDE type.)

2) Is it merely a matter of somehow setting the interrupts each drive uses,
   providing the BIOS and address setting are correct?  Could it be as simple
   as getting a ribbon cable with with a twist in it?

3) Can anyone provide me with details about the jumpers on my drives?  The
   models are

        Seagate ST-251 (~42 M, MFM), which has 7 un-labeled jumpers)

        Western Digital 93044 (~42 M, IDE), which has 3 jumpers, '2, 4, 6'.)

4) Should I give it up and just sell the drives for cash to buy one big one?

5) Since this is not strictly a 'forsale' item, where else should this be
   posted?

Much thanks in advance for any help provided.

	They are DON'T CARE's. The drive will just ignore whatever you put in.
This is because of the nature of how IDE drives work. All that stuff is
actually hidden from the bios and done locally on the drive. Remember, you are
already faking out the bios when you assign the head, tracks and cylinders and
letting the drive itself figure where the data really goes. 


	I've seen various reccomendations. Usually either 0 or the max cylinder
number. I use 0.

Subject: ET4000 manual question
Organization: St. Louis Univ.
Date: Wed, 2 Sep 1992 15:37:37 GMT


I have a video card from an unnamed Taiwan company.
It has an ET4000AX  TC6059AF  9208EAI  chip on it.
It has an ICS 2494N chip using a 14.XX818 XTAL.
It has a MUSIC  TR9C1710-80PCA DAC chip.
It implements a VESA system.
It has a SYNC BIOS chip with the following:
BT005   WKED-SYA   205CNF2C0C and a 256K EPROM and 1Mb of ram.
The ROM is based at C000:0 and has ET4000 VESA 1/10/92 V8.02X
The board does not appear to have any "PAL's"
in the decode logic, unless they are in the "SYNC BIOS" chip.
There are no other copyrights save for Tseng Labs.
It came with a dmode program on a floppy with a TSENGLABS
INT'L CO LTD copyright. The dmode program is version 2.5
and states that it is for MegaVGA or MegaEGA cards.
This program will set the card to do 1024x768x256 and 70 Hz refresh
(mode 38). And both VGA card and monitor work acceptably under DOS.

I am running X386 1.2E (a port of MIT's X11R5 for ISA Bus PC's)
with 386BSD (a port of UC Berkeley's NET2 software)
and can program the card for 640x480 and
800x600 using the default boot up settings and whatever the card
does or does not do with the register bit twiddling already built into X386.

I would like to program the system to work properly at 1024x768 or so
but cannot get it set up quite right. I believe i need to tell the chip
and dot clock VCO to work at a higher frequency.
Is there an engineering example in the et4000 handbook that is similar
using the chips mentioned.
And if so, are there register level programming descriptions available.

If there is information available, how may i obtain it, and
may it be distributed to other institutions?
I would expect that quite a few other people would
be interested in doing the same thing, as ET4000 chip cards were
recommended for X386. However, the cards that i find available now
use the VCO rather than a bunch of separate clocks.

Thanks again.

Occasionally my hard disk makes an ugly racket (the heads buzz around
insanely) for a while, during which time it is unusable. Until today, 
these episodes were mercifully short and uneventful, but this evening
I turned my machine on, the disk began to buzz continuously, and it would
not boot up. In fact, it eventually reported a failure for drive C: to
respond. Fortunately, after many attempts, I got the thing booted and
most -- but not all -- of my files were intact. NDD now reports many
bad clusters whereas before this latest incident there were none :-( 
(and some files have been eviscerated, with their entrails strewn
over other files, directories, etc.)

My system is still under warrantee so I should be able to get a free
(or at least cheap) replacement, but I was wondering if anyone else out
there has experienced a malfunction like this. If 20000 hours MTBF is
supposed to be the average, I wonder what the spread is....

I believe the problem is releated to the fact that when the 286 chip 
was designed, they made the old real mode for accessing memory below 
1 meg and the new protected mode for everything else.  They assumed that
the 286 protected mode was going to be so wonderful that there would be
no turning back, and so made no instructions to take a 286 back out
of protected mode.  This made it so that no dos programs could use 
memory above 1 meg.  But some programmers at Quaterdeck figured out
a neat trick.  The keyboard controller could be programmed in such a manner
that it will pop the 286 back into real mode at the mere cost of 200
some clock cycles. (That is pretty awful, actually.)  

I imagine since himem.sys manages extended memory, it will want to talk 
to the keyboard controller on a 286 computer.  I believe that intel got 
wise with the 386 chip and made instructions that work more efficently 
that programming the keyboard controller to trigger an interrupt to throw 
the computer back into real mode.

And you all thought the A20 story was hairy.
Until the 386 chip, intel designed some real junk.
They would have thankfully have gone broke if
IBM hadn't decided to use the 8088 in the PC.
Now they are a moster company that can pour billions
of dollars into making cisc computers run with nasty 
anscestry run really fast.

I use RLL controller (26 sectors/track) and I'd like to use this in my computer

17 sectors. Bios is Award but type 48 don't work.
So the problem is that after low-level I try fdisk but it thinks my drive is
1024 cyl 8 heads and 17 sec = 68 Mbytes. While it is 26 sectors and 104 Mbytes
And ofcourse it won't boot up. I can low-level format my drive with 17 sectors
(WDfmt allow to do that) but I want use full capasity. So any opinnion about
what to do next?

I have purchased a 486DX/50 Insight system.  My experience was that
the hardware was generally excellent.  I was somewhat disappointed by the
support though.  I bought the system to run OS/2 and when my printer did
not work I called them.  The response that I got was that they use DOS and
couldn't really help me with anything else.  From prior experience with
other systems and a long session with IBM on the phone we determined that 
the IO card was not compatible with OS/2.  Insight could offer no
replacement though they did take the old card back for a full refund.  I
had to find my own compatible card without their assistance.  They also
sold me some OS/2 drivers for my hard disk controller that were not
necessary.  they also took these back for a full refund.  

IN summary, good hardware, but not good support unless you are running
DOS.

lil bugger is plugged into the correct place (On PS/2s the mouse port is
stupidly identical), and if that doesnt help, try tapping each key once or 
twice to unstick any that might be stuck.  Then look for water, Hydrochloric

Get it serviced or (better yet) throw it out the window.

Is this a limitation of the hardware design of the tape drive or is there
software out there that can make the tape drive "smarter" and allow volumes
to be deleted and/or overwritten.

I also have another question. I'm planning to add 2 more megs of RAM to my
