   Two possibilities come to mind: 1)The diskette you used to recreate the
partitions etc. could be infected. 2)Stoned is relocating your partition
table so fdisk writes are being redirected.
   To kill the virus you need to boot off of a CLEAN, WRITE-PROTECTED 
diskette (go buy a new copy of DOS if thats the only way you can be sure).
Then "scrub" the partition table by using this program:
 Run DEBUG.COM and type the following (excluding '-') putting an <enter>
after each line:
-A
   mov dx,80
   mov cx,1
   mov ax,0301
   mov bx,100
   int 13
   int 20
   <enter>
-g=100
-q

You have just created and run a program which will overwrite the partition
with itself, allowing you to FDISK the drive.
   Also, the files you backed up may be infected so they must be checked and
cleaned before you use them.

 If I had a choice, say between an elcheapo monitor which supposedly
was noninterlaced(big IF), or one equally priced higher quality one
that didn't claim to be noninterlaced, I would go with the higher
quality, over unsubstantiated claims.


 Most claims on non-interlaced come into play with 1024x768 resolution
anyway.  This resolution is virtually unusable on a 14" monitor anyway.
It's just too small.  Plus except for Windows there is little software
which will drive these higher resolution modes anyway.

 A lot of this depends on your intended usage.

 If you want 1024x768 go with a 17" monitor.  If you want 1280x1024,
go with a 20".

 If you're going to spend this much money on a computer, at least get
some quality.  Also, don't skimp on the video card.  i.e. skip over
Oak and Trident $30 specials.

I wonder why nobody consider Hayes 14.4K modem. I tried a Hayes 9600 modem 
which works ok with another same type of modem at 9600 baud rate. But when
I tried to use it to dial in University's 9600 modem (unknown type), the 
connection rate decrease to 2400 baud. Does Hayes only talk to its own in
high speed or something else is not set up right?

My problem is that I need to prevent SCO from taking over the boot partition

I'm helping a friend part out an old Sun 386i.  He's got a 14" monitor

I'm guessing that a standard ET4000 SVGA card will work fine with this
monitor.  But I though I'd gather the collective wisdome of the net
just incase I'm missing something stupid.

Also, the mouse and keyboard have non-standard connectors.  Anyone know
if they can be adapted to work on a "normal" 386.

Any help/ past experience would be appreciated.

I still haven't found out why my monitor flickers after installing a 486/33 
motherboard.  I have tried reducing the bus' clock speed from 8.33mhz to 
5.55mhz, but it still flickers.  The monitor will flicker in 80x25 text mode
and naturally in VGA mode.  It doesn't start to flicker right away.  Instead,
it seems to take a few minutes before it's noticiable.  I was sitting closer
to the computer and monitor tonight, so I noticed a 'whining' noise coming 
from the monitor or the computer when the screen was flickering.  The monitor
is about two years old as are most of the computer parts except for the  
motherboard, the SVGA card, and the IO card.  Any one have any more 
suggestions?

Speeding up computers is a topic which comes up often.
It's generally a bad idea.

Any time you try to run a computer at more than its rated speed you are
playing with fire. The manufacturer can sell faster parts for more money
than slow parts. So if the parts are capable of running at the higher
speed they would have beed rated for that speed originally.

Often the different speed grades of a part are all made on the same
line. They are then tested for how fast they will operate. The ones that
fail the high speed tests are sold as lower speed parts. Its foolish
to try and use these parts at a speed at which they failed the
manufacturer's tests.


failed their tests.

486 DX 50 and why not a DX2 66. But as I read the news it seems to me that chosing a
motherboard is not so simple. I would like help from you !!!
	
	I'm looking for an AT BUS motherboard, and I don't need (for the moment) a
local bus. What kind of bios should I look for (AMI, PHOENIX, ...) Is there any
problems with the DX 50 and DX2 66 memory speed (60 70 80 ns ?) what type of RAM chip
should I buy (3 chips SIMM ?) I need to know what kind of cache is better ? (external,
64k, 128K or 256K ?). Is it possible to put a DX 50 or DX2 66 in a "desktop box" regarding
heat ?? 


	Finally what vendor's model do you suggest me ?


PS. I'm running Linux, and I want to run big software as Khoros etc .... under X386.


	Any help will be welcome. You can reply by email or posting to this groupe.

Keywords: 6845
Organization: Computer Science Department, University of Cape Town
Date: Tue, 29 Sep 1992 11:34:42 GMT

I've been having some problems with a scrolling program I wrote in C.

It scrolls text in 80x50 trafics mode. (Er, normal text mode using upper and 
lower bar chars.)

Now seeing it's using text mode and I'm accessing screen memory direct, I 
wanted to make it work on both CGA/EGA/VGA type screens and monochrome 
screens. Each of these cards has a 6845 or some emulation of it.

I use port 3DA, bit 3 to detect the vertical sync pulse and immediately do
the screen write, which makes for *very* smooth scrolling. On my Oak SVGA, 
my program works both in native VGA mode, and in emulation of Mono mode. In 
mono, the program uses port 3BA, obviously, but my SVGA emulates the 6845 at 
3BA, so it all works as expected.

Problem: On a PROPER mono card, it doesn't work! I've tried and tried again;
port 3BA is the documented port for the 6845 status register, bit 3 is what
I'm checking, but either the bit is always 0, in which case my program hangs,
waiting for the sync pulse, or it's always 1, in which case it scrolls at
high speed, flickering wildly.

I suspect there is another way to detect the mono sync pulse, which works, 
and that my SVGA duplicates its 6845-equivalent wrongly - ie. the status 
register sync bit *isn't* used in a mono card, and my SVGA *is*.

What I would like is 1. An explanation of why this goes wrong, and 
2. The correct way to detect a sync pulse on a mono card.

Please EMail me at agodfrey@cs1.uct.ac.za rather than posting.

There's been so much talk about the quality of NEC MS 4FG monitors
that I have decided to do a poll on what owners of this monitor think.
If you are an owner of a 4FG, please respond via e-mail to this post
with the following information:

1. Did the monitor have problems when it arrived? If so state specifically
   what those problems were.

2. Were those problems resolved to your satisfaction?

3. Would you buy another one?

4. Would you recommend someone without one to get one?

I will post the comprehensive results of this poll next week. The more
people who respond the more valid the results will be. If you want to
respond concerning the 3FG or 5 thru 6FG go ahead but clearly state
that you are doing so and I will deal with those results separately.
Hopefully this poll will give us a good idea about the quality of NECs
hardware and their "after service". Thanks in advance.

This depends on what OS you're running.  For DOS, you are probably
correct.  You'll get more speed with a hardware cache.  However, that
isn't necessarily true for any OS which does preemptive multitasking,
since the OS will include a cache area and the controller can use
that.  With a bus-mastered controller and a software cache that works
well, you will get as much speed without the cache.  This is possible
because the SCSI bus-master will get the read commands and go on about
it's business funnelling things through the cache into motherboard
memory.  

Tests have indicated that in a lot of cases, running UNIX WITHOUT a
caching controller is faster than trying to use one (because UNIX
understands more about the way it uses the disk than a hardware
controller can, so it caches more efficiently).  I can't say for
certain, but I suspect that the same thing might be true for OS/2.

maybe it's taking longer because of compression.

  Assuming the cache is actually present, Checkit is going through it to

not possible.  Any suggestions?

Hi, 
  I swapped a floppy drive on a 286 computer, and got what is apparently,
an unrelated problem.
  The start up goes through the normal testing routine everything is OK,
checks the first floppy, then the second, all normal, than it gets to
the hard drive, the light goes on and not off.  Eventually it beeps with
the number 1701 on the screen.  Shortly afterwards it requests to have
a disk placed in drive A: and press any key to boot.  I understand this
as the BIOS not finding being able to communicate with the hard drive.
I checked and double checked the cables, especially the smaller one, that
looked like it had been pulled out a bit, but that didn't help.
The hard disk and floppy disk controllers are separate cards.

The BIOS is Award BIOS 3.03.

What could have gone wrong?  Was it just dumb luck that it happened to
fail when I took the cover off or did I pull something loose?  And what is
code 1701?

Thanks in advance,

Mitch Dernis
