If you need "info" about programming SVGA modes then i suggest
you try and get VGAKITxx from SIMTEL20. It shows clearly how
to access the video memory of all these SVGA boards (in contains
code for it).

Short answer:
Yes: It is different for EVERY brand of SVGA chipset.
The memory will be accessed in 64K banks, at segment address 0xa000,
where the Bank-switching will be different for all SVGA chipsets.
The 16 colour mode 800x600 is mostly without bank switching.
The 16 colour mode 1024x768 is sometimes without bank switching (but
in that case means accessing MORE then 64K memory.

If you can, use VGAKIT. Good luck,

Hello fellow netters,
  I am currently looking at puchasing a SVGA card.  I have been debating 
between the Diamond Speedstar 24 and the Orchid Prodesigner IIs.  I have 
heard good things about the Diamond card, but have also heard that it can
be hard to configure (tougher than most cards), and that it causes problems
with MS Windows, and O/S 2.  I have not heard much about the Orchid card.
I would like to know what you guys think of these two cards, any problems 
that you have had, or anything else you would like to say about them.  I have
found that I can purchase both cards for about the same price.  Please respond 
via e-mail or News.


Thanks for your time,

I take it this is to avoid the Microsoft HMA kludge; can those of us

Since I'm planning on taking some PC equipment & peripherals from the U.S.
(120 V, 60 Hz) to Germany (220 V, 50 Hz), I'd like to know which components
and peripherals will not work correctly and should not be taken along,
because they depend on the 60-Hz line frequency, which a step-down voltage
converter cannot take care of.

I hear that monitors and dot matrix printers will not work correctly.
Is that correct? What about other components, like internal tape backup
drives, hard drives, floppy drives, etc.

What about an external high-speed fax/data modem?

What about CD-ROM drives (internal or external)?

My power supply says "High Frequency Switching Type", no further information.
Does that mean I'll just need an adapter, and not even a voltage step-down
converter to plug it in?

  Vaguely related question:  What is the ratio of full cycle time to

Yes, I just read about this in a magazine at work.  I forget the name of 
the magazine but I think it was possibly _PC_Week_ Aug.??.  Anyway, they 
basically said that Microsoft is planning on producing a Microsoft sound 
card to be used with their multimedia windows stuff.  They said Microsoft 
will also be supporting sound cards such as the Soundblaster in the same
package.  Unfortunately I can not remember any more and I won't be able
to view the magazine again for at least 3 weeks (unless they throw it
away).

No price was mentioned, and the expected release date was also not mentioned.

What is the difference between a DX and a SX specification for 386 and

structure. However, any 386 or 486 can address the memory in either
8,16, or 32 bits bus structure.

By the way, is there any difference between a 386 and 486 except that
486 has some catch memory inside chip?

Hi all...
I want to ask 2 questions:
The first one is about the 286 models with 20/25 Mhz speed.I was told that
they aren't good.Is this true? I was told that this processor with THIS
speed can make problems when copying/deleting/editing stuff.Again:Is it
true?
  Or with other words: What should I preffer:286 with 16/21 or 20/25?
TThanx.
Now to the second question:A friend of mine wanted to uppgrade his VGA card
memory to 1 Mb.He thought he have 512K,but at the store he was told that
he have an old card ,with 215k on it,and if he wanna upgrade to 1 Mb,he
should change the VGA card.Another thing that's going on,that this poor guy
sees ,vaguely but still annoyng,some kind of circles which exists usually when
you use anti-glare screens...And it is VGA,that should have good resolution.
Now ,the seller told him that the circles are because the card
"don't transsmit on the same frequency as the VGA receives" (or something like
that). Now,my question: Is this seller just a crook who wants to sell
VGA cards to people who don't need it,or,if he is right,explain me what
that thing mean?
Thanx a lot

The SCSI will only use one interrupt for each host card, and you can
drive 6 devices off of each host.  Yes, the IDE/SCSI combination would
use two ints.

I'm just about out of 8 bit INTs (i.e. XTs), but I've got enough
16-bit INTs free that I could fill out the rest of my empty slots and
still have a few left over.  The problem for me is that I want a
Soundblaster card.  I'm full (or will be) in the 8-bit INT department.
One serial, two parallel, and a bus mouse, and no more 8-bit
interrupts.  So the regular Soundblaster card is out, and I have to
pay an extra $100 to go with the 16 bit card.  So it's not as bad
as it could be.

I picked up the Preliminary Release of Windows NT, and Im
impressed enough to put together a system.  In the longer
term future, if Microsoft or SGI really does make OpenGL
available, Id like to get something like an i860 graphics
board capable of 24-bit color.  The problem is the bus.  Im
pretty sure the old SGI 3000 series boxes just used VME to
talk to the graphics subsystem, and the processors were dead
slow, yet they had great performance.  Given that most of
the rendering would be on the board I see no reason why EISA
wouldnt be able to handle it.

So now that its "predict the future" time, I need some
information on the past.  How popular has EISA become?  Ive
heard that 50% of the cards that are available are SCSI
controllers, which doesnt speak for diversity.  Id rather not
wait till VESA gets standardized, chips come out and they
start to come down in price, yet Id like to put together a
system that I can expand over time (the box Im looking at has
a replacable processor module so I could put a P5 in it.
The graphics adapter is my only other concern.)

Also, are there any EISA graphics adapters that support the
display memory as a linearly addressable region?  Its my
understanding that VGA breaks the display up into non-rectagular
regions which make any drawing operation a painful sequence
of bank switching operations.

General opinions about EISA, current 24-bit solutions, etc...
are appreciated.  -Steve

Have you tried disabling 0 wait state?  I was having problems until
I did this.  It was only a 5% performance hit.  Also, there is
a dip switch for "alternate (bus) timing", and a jumper for 16/8
bit bios access.  I'd try various combinations of these (starting
with disabling 0 ws) and see if that solves the problem.

I've just gone through my third Gateway CrystalSCAN 1024 monitor in
two and one-half years.  Since Gateway only warrantees replacement
monitors for 30 days, this one was months beyond any warrantee.
A friend of mine has exactly the same system that I have, and he's
on his third monitor.

When I called Gateway Tech support with questions about how other
CrystalSCAN monitors have been holding up, they told me that they
"get a lot of abuse," whatever that means.  I was curious, because
at this point I was wondering whether it was the monitor or something
in my system that was causing these failures.

Has anyone else had any failures with the CrystalSCAN 1024 monitor?

As a post-script, I looked into repairing my monitor and found only
one place that would touch it, and that was for a $300 estimate!
I saved my money and bought a comparable Packard-Bell monitor.  At
