I too am trying to help a friend get a XT controller working on
an AT.  and we too found that setting drive types to none, made
the drive boot.  Its still kind of odd, because it won't boot
thru to floppy if there is one in the drive, and you can't
do a control-c to stop AUTOEXEC.BAT.  

But regarding the interleave, I think the problem may be that
the XT card has an 8 bit ROM BIOS, while the AT cards have a 16
bit wide one.  Anycase, doing two fetches to get a word would slow
down the AT.  In my researches, I found a program in the archives
(garbo I think it was) called RAMIT66.ZIP.  what this did was copy
the ROM BIOS to RAM, making certain translations.  This lets the AT
run at full speed and this may let you get back up to 3:1 interleave
or better.

I saw a reference by someone to DISABLING the cards BIOS completely
to let the 8 bit card do its stuff.  Is it possible that AT's contain
the code to drive disk controllers without BIOSes, and using the
BIOS just screws things up.  A jumper was mentioned to disable
the BIOS.  Anyone know what the story is on this?

I am looking for an IBM (compatible) interface that I want to use in a special

and I would really appreciate if anybody could help me with that.

As I said , I am looking for an interface that would allow me to close or
open a circuit (external circuit) by means of sending a certain value to a
memory port. This means that I would like the interface to have some kind of
switch or something similar so that when I use that certain port , I would 
have the switch to be closed or open.

If there are no such interfaces , then could anybody tell me how could I do
this using the COM or LPT port (if this is possible).

Again , I would be really grateful if somebody could post this for me here
or mail me any information regarding this subject (such as price and a few

Subject: 386DX/33 twice as fast as 486DX/33
Organization: Intergraph Corporation, Huntsville, AL.
Date: Sat, 9 Jan 1993 17:25:11 GMT


I was thinking about upgrading my 386DX/33 with a cheap 486DX/33
motherboard.  The two things I wanted to go faster were games
(had to turn off clouds in Comanche Maximum Overkill) and
JPEG.  So I ran some tests on a friend's Taiwanese 486DX/33
of unknown chipset:

386 - Swan 386DX/33, Micronics MB with either 32 or 64K cache (I'm ashamed 
      to admit I'm not sure which, salesman said 32K, magazine review said
      64K, manual says both are possible), Intel cache controller,  
      8MB ram, Pheonix bios

486 - noname 486DX/33, Taiwanese MB of unknown chipset, 256K external cache,
      16MB ram, AMI bios

Tests:

Tests were run on bare dos 5.0 with minimal stuff in config files:

I used the Independent JPEG Group vesion4 jpeg code, compiled with
the Intel 386/486 C Codebuilder (32bit extended dos) compiler.
The jpeg stuff is not disk bound, and besides, both systems have
comparatively fast IDE drives.  Timing was done with a stopwatch.
lake2.gif is 630x422x256.

cjpeg -Q 80 lake2.gif:

386: 15.0 sec
486: 29.7 sec

djpeg lake2.jpg:

386: 23.3 sec
486: 47.3 sec

The other benchmark results were more reasonable, but these
were canned benchmarks, not real-world tests.

Norton 4.0 cpu index:

386: 42.7
486: 54.2      

Norton 5.0 cpu index:

386: 35.4
486: 72.1

Does anyone have a clue as to why the 486 was twice as slow on the jpeg
stuff?  I know the Intel cache controller on my 386 uses posted writes for 
0ws writes 100% of the time, and the 486's external cache may be 
write-through, but shouldn't the internal writeback cache in the 486 buffer 
the effects of this, if the 486's external cache is indeed write-through.

I bought my last Gateway system from them about 1.5 yrs ago and
I've been talking to them about a new 66V system and have noticed
something - they will NOT lower their price!  The guy I used to deal

old salesman back and see if maybe it was just him, but has anyone
else noticed that they are more steadfast in their pricing? (I have
bought about 3 systems from that salesman over the years and always
got at least $200 off the total delivered price)

One more thing - the lead time on the 66DX2 systems custom
configured is *3 weeks* !!! Jeez.  I was going to order it today
until I heard that.

Organization: Acadia University
Date: Thu, 7 Jan 1993 16:19:00 GMT

I bought a NEC 4FG in November of last year and I had to bring it back 
because the picture was tilted downward on the left side of the screen and 
the upper corners were unfocused. The monitor was taken to a NEC service 
center for adjustment and when I picked it up, the picture was tilted to the 
right and was still blurry in the upper corners. The "technician" told me 
that he didn't have the equipment to set up the monitor properly so I took 
it back to where I puchased it. A new monitor was sent down from NEC and I 
when I tried it, it has the exact same problems as the first plus an upwards 
bowing at the bottom of the screen. The store where I bought the monitor 
called NEC again and were told to take the new monitor to the same service 
center, and that NEC would fax the necessary information to the service 
center to enable them to set up the monitor properly. Somehow I don't think 
that this is going to work. Has anybody experienced similar problems? Does 
NEC have sort of quality control problems? I still don't have my monitor 
back and have to use a standard VGA monitor which the store loaned me. This 
is not the kind of quality I expected from a monitor for which I paid 
approximately $1000.

A while back I posted in some detail of problems I was having getting
a 120MB CMS Trakker unit to work.  Since then, I sent it back to CMS
for them to take a look at it.  The customer service in this firm is
first rate, and many people took a lot of time to help me with the 
problem.

The bottom line is that the problem is really not CMS's.  The unit is
very sensitive to el-cheapo serial/parallel cards, and the unit requires 
that LPT1 be properly supported with IRQ circuits and logic on the board.  
If you can't select among and between IRQs  for LPT1, your Trakker probably 
will not work.  (As an aside, I also find that such boards don't work with 
parallel port hardware locks either - or at least not reliably) 

So far I have tested
four different manufactures of cards and have found problems with three 
of them.  Once I find a solid supplier, I will let the network know.

Some manufactures are in fact selling 33MHz Intel CPUs with a 40MHz clock.  I
would not trust it though.  If the CPUs were stable at that sort of speed, then
Intel would have sold them at that sort of speed.

If you do intend to try it, and your old clock is 33MHz, you will probably find
that the crystal unit is actually 66MHz, the speed of the crystal unit is divided
by 2.  So if you put in a 40MHz unit, your board will divide it down to 20MHz. 
There is probably a jumper to turn the divide by 2 off.

If you do try it, fit a heatsink to the CPU and keep an eye on the temp of the
CPU.  Let me know how you get on.
