i have heard that NE2100 ethernet card is more relaible than WD8013.
i have seen ads for NE1000/NE2000 but not a NE2100, two questions for
somebody who knows?

1. where can i find more info on NE2100?
2. where can i find vendor info (with some idea about price)?

thanks in advance,

This MFM controller will definitely work on an XT1140. However,
you will not able to use the extended capacity of the drive (XT1140's
can usually be formatted to 1224 cylinders) unless you use a BIOS
extended such as the one in SpeedStor or Disk Mangler.

I'm looking for a disk benchmark program that will give

latest Coretest but I find the results I get from it are a 
little hard to believe.  With my Micronics 486-33 VL-BUS and 
an UltraStor 34F VL-BUS Fast SCSI-II Host Adapter
                    
controlling a Quantum 240S, I was getting HDTR of over
25 MB/sec!  At the end of the test, I of course received
the message that the rates were inaccurate because of
caching.  This must be due to the built in 256K Cache the
Quantum drive has on it.
 
I've also tried Norton 6.02's SI and got over 1.4 MB/sec.
After the test I got a "controller blocking" something
something message.  Pc Tools 7.1's SI gave me close to 1.2 
MB/sec.
 
I have heard of a benchmark called BYTE.  Will this puppy do 
the trick?  If so can someone direct me to an ftp site and 
directory where I can find it?

Well, that's not quite right, either.  What I suspect happens (I'm not
in the semiconductor biz) is that Intel tests all its parts at 33 MHz
UNTIL THEY HAVE THE NUMBER OF 33 MHZ PARTS THEY WANT TO SHIP.  Then,
all the failures PLUS UNTESTED CHIPS are tested at lower speeds.

Note that this doesn't necessarily apply to all parts (i486-50DX parts
use a different fab process than 33DX parts).

Gateway offers a card that you can get that has a game port as well as extra ports for additional serial and parallel interfaces if you need them.  I think the price on the card is about $25 or $30.  And if you plan on playing games, some sound cards such as the Soundblaster Pro have a built-in joystick port.

I don't know if the full-size boards are still made. but it makes no
difference because the baby AT board uses the standard mounting holes
but fewer of them.  It simply doesn't extend under the drives in a
full-size case.

Do check that the power connector is standard.  Some manufacturers used
block-type connectors.  You can make an adaptor, but it's a pain.

If you're not planning on doing any kind of multitasking, not much.
Otherwise, what you gain is the ability for an EISA SCSI controller to
be working at the same time as your VL video board.  Failing that,
you'll have to settle for ISA controllers (which isn't all that bad
for single devices).  Just keep in mind that only one VL board can

Don't see why it would be a problem.  Of course, I'm not sure why you
need a 17" VL VESA video system to do games that only use 300x200x256.

Article-I.D.: cs.C07MvC.8M4.1
Organization: School of Computer Science, Carnegie Mellon

We are always looking for "the best card" when we want the best in
video performance, but is it really enough? Can benchmarks provide
true-to-life performance indices? The answer is really more
complicated, because  as I found out, it does not depend only on the
graphic card beeing used [read on...]

I have performed the following tests on a 486 DX2-66 Machine with an
ATI Ulta Pro Local Bus video card.

When I used Winben25 I found out that the only thing relevant to the
results was the resolution in which the tests were run. In other words
the system configuration is irrelevant and thus does not impact the
results. The results I got were 17MWinmarks in 1024x768 which is what
you should expect, if I am not wrong. That is with the build43 driver
for the ATI, which is pretty old.

The interresting results come from running the new BYTE benchmarks.
The BYTE benchmark run in Standard VGA, not thru windows and the
results are given as an index factor compared to a Compaq.

I have run the tests in many modes and got the following results:

Shadow of video ROM disabled and no copy of BIOS in RAM:.........0.19
Shadow of video ROM enabled  and no copy of BIOS in RAM:.........1.10
Shadow of video ROM enabled/disabled and copy of BIOS in LOW RAM:1.90
Shadow of video ROM enabled/disabled and copy of BIOS in HI  RAM:1.34

Explanations:
==============
To copy the BIOS into RAM by software you use the RAMBIOS.SYS driver
in the CONFIG.SYS file. It can be either loaded in the bottom 640K
with DEVICE=RAMBIOS.SYS or in upper memory with
DEVICEHIGH=RAMBIOS.SYS.
When the RAMBIOS>SYS is loaded it is used instead of theHardware
shadow, as the results also show.

Questions:
============
1) Why is there a difference in the index between the SHADOW index and
the copy into high RAM? I would think these should be exactly the
same.

2) Why is there such a high increase in performance when copying to
LOW RAM? I know that caching is enabled also to upper memory, is there
a different scheme for caching low and high RAM ???

Ultimate performance is 
=========================
...achieved by copying the BIOS into LOW RAM which makes me wonder why
do we need HARDWARE shadowing if it does not make things as fast as
they can be???????

Hello Everyone;
	Let me cut in if I may, and hopefully ican help in a way.  Fisrt
of all I missed the original question.  Secondly, what are you really
going to do is also important.  I think buying the 486SX is for those
less money, and they can easily upgrade their system later on.  In terms
of speed I think it is fast enough to do some Graphical Software (except
AutoCAD you still can it is a little bit slower).  If I am going to buy
one, with less money I have, I will but the 486SX motherboard with
compatible with DX266.  I believe, you can purchase a 486sx mother board
for less than $250.00 with CPU

 I am aware that ASPI originated at Adaptec, unfortunately when I spoke

running with the Adaptec 1700 (EISA) series of adapters!?

Have you tried using the Corel drivers with your board? Maybe the problem is
 just some remote glitch but 99% of the functionality is OK (but I doubt it)?

No, not exactly clock-doubled, but the chip that Motorola labels "25MHz"
