On my 386 AMI BIOS (2/90 or 24Dec90, depending on whose date you count
:) ) it is called "Concurrent Refresh" (No relation... ) vs. "AT Style
Refresh".

My default was "Concurrent Refresh" and that worked fine with 1Mx9 9
chip SIMMS. When I added some 1Mx9 3 chip SIMMS, the world fell apart!
By setting "AT Style Refresh" sanity was restored.

It was suggested to me that this setting affects how many address lines
get refreshed, and that the BIOS KNOWS that it needs to refresh all of
them for 4Mx9 SIMMS, but doesn't recognise that it needs to do so for the
newer 3 chip 1Mx9 SIMMS (hence you have to tell it...).

I found that when the settings were wrong, and I had "parity checking"
enabled, that I got lots of parity errors - which got worse as the
machine warmed up. Windows 3.1 wasn't terribly happy either....

That is what I found, anyway....

Date: Sat, 23 Jan 1993 02:44:24 GMT
Organization: Hewlett-Packard
X-Newsreader: TIN [version 1.1 PL8.1]

I just ordered a Gateway 2000 486-66V, so I figure I have a while to shop
around for a monitor :)  I would have ordered their Mitsubishi 20" Diamond
Scan monitor model #6945, but when I called Mitsubishi they said that they
have upgraded that model to the HL6955SETK (which include anti-glare and 
anti-static coating) and that they don't sell the 6945 anymore.  Gateway,
which would charge about $2210 for it said they couldnt get the newer model.
So I am looking elsewhere.

If you have any opinions, pro or con, about the following monitors, please
let me know.  If you can fill in some missing info on each monitor, I would
appreciate it.  Also, if you know of a magazine that has reviewed 20 inch
monitors, please let me know.

All of these monitors *should* be non-interlaced, multiscanning or multisync
monitors with a minimum maximum resolution of 1280x1024.  Correct, if wrong.

Maker & Model Number	Size	Dot	Refresh	Special		Emission
				Pitch   Rate At	Features	Standards
					Max Res
====================	====	======	=======	========	=========
Mitsubishi HL6955SETK	20"	0.31mm	
(Diamond Scan 20)

Mitsubishi HL7955SBK	20"	0.31mm
(Diamond Pro 20)

Nanao T660i		20"	0.31mm	75Hz	Trinitron	MPR2;TCO

Nanao F750i		21"	0.31mm	

NEC 6FG			21"	0.28mm	74Hz	

Sony GDM-1936		20"	0.30mm		Trinitron


I had the Radius 20/S on the list, but a salesperson said that it was exactly
the same as a Sony GDM-1936, but $500 more.  Also had ViewSonic on the
list, but their maximum refresh rate at 1280x1024 was 60Hz.

Is Trinitron really better for simple Windows applications and fonts?  Does 
that square pixel really help non-CAD programs?

How important is maximum horizontal and vertical frequencies, as well as 
bandwidth?  The Diamond Pro says it can do 78kHz horiz, 130Hz vertical
and 130mHz bandwidth.  How does this info relate to its max refresh rate at
the max resolution?

Can you hook up BNC cables to the ATI Ultra Pro video card on a Gateway?

Any recommendations for mail order firms for monitor?  Any to avoid?

Thanks in advance for any help you can provide!

Date: Wed, 27 Jan 1993 22:19:37 GMT


I am seriously thinking about getting a high-end 486 system; however, the Local Bus
hype has me a little worried. Many reviewers regard it as the best thing since sliced bread,
but many competent dealers I have talked to told me to stay away from Local Bus sytems at this point in time,
even though they  are selling such systems themselves. The so called VESA Standard seems
to contain a lot of lose ends (and few people have actually seen the specs).

Here is my concrete question. I have heard the VESA Standard specifies the clock to be max. 40Mhz.
On the other hand a lot of machines are advertised as true  (486DX-50) 50Mhz machines with
VESA Local Bus. Do they just run the Local Bus at a higher than spec frequency, or do they half the clock?
Many of the big mailorder houses  sell 486DX-33 or 486DX2-66 machines with Local Bus, but no 486DX-50.
Is the potential incompatibility at 50Mhz the reason they don't offer such systems? 
Anybody out there who knows what's going on?

I have a 486-66, ALI-M1409 chipset motherboard with 1991 AMI bios
and ISA bus

It had 4 1Meg SIMMs in bank 0 which I assume are 1Mx9 ( 30 pins 3 chips, 
2 the same and 1 different)  and everything was fine with this config.
I then added 4 1Mx9 70nS SIMMs in bank 1 and the system now tells me that
I only have 1Meg of RAM and no extended memory.
If I take the SIMMs out of bank 1 it goes back to 4Meg again
There are no DIP switches on the board for memory config and the manual
simply says run cmos setup after adding memory.

The new SIMMs look slightly different to the old SIMMS in as much as the
old SIMMs have 3 chips all the same size with 8 legs on each side
2off Pt no.- HM514400AS7
1off Pt no.- HM511000AJP7

new SIMMs have 3 chips 2 large, 1 small with 4 legs on each side
2off Pt No.- M514256A-80J   (OKI)
1off Pt No.- M51C256-80     (OKI)

Is there a kind soul out there who can wave a magic wand and solve this
problem. Any help would be greatly appreciated.

Greetings...

(1)  How often do you *clean* your floppy drive(s)?
(2)  How *old* is the drive?
(3)  If it's very old (3+ years), you may want to replace it (approx.  $60).

A floppy drive should be cleaned every 10 hours of use.  You can get a
drive cleaning kit at your local computer store, radio shack, kmart, etc.

The older drives were not as well made, and some of the brands were (and
still are) just plain unrealiable.  Try Teacs, Mitsumi, Toshiba...

Off chance:  Could be your *controller* is getting old...  
Off chance 2:  I've seen this twice (in 8 years):  dust build up inside
  the case (*large* amounts, Aunt Clara *would not* be happy...); clean
  out the dust; end of problems.  Seems dust is a low-level
  semiconductor.

Good luck!

   They say you can run them sideways, but should reformat them before use.
This was true for the big clunky drives, in days of old, due to gravity on the
w/r arm.  This may not apply to newer drives which have less mass on the arm,
and are generally put together better.  However, I'm still running mine the

WHAT? Maybe someone can correct me on this, but this looks suspiciously
like 256K, 80nS RAM instead of 1M, 70nS.  Test it out: remove the old
SIMMs and plug these into bank 0.  If it test 1Mb, you've been cheated.

I read that yesterday, and it gave me a good laugh.  Though I really do think
the majority of GW systems are shipping out on time - I spoke to someone
yesterday who ordered a 66V first week of January, was told he'd get it
first week of February, got it Jan. 15th - anybody who says that they aren't
having shipping delays is sadly deluded.  There's an article in InfoWorld
this week that tells all about GW's shipping problems and the increasing
number of customer complaints popping up on bulletin boards.  As I've said
before, though, I think the biggest problem is not the delays - as the PC
Mag says, Compaq and IBM are also having serious delays - but how GW is
treating customers re the delays.

>BTW, in this issue Gateway 2000, along with 6 others, win the PC Magazine

Well, that's merely a sign that over the long haul, GW has treated its
customers well.  Its only recently that all these problems have popped
up.  Hopefully for GW and its customers, they will solve these problems.
