Okay, I apologize for any sort of wasted bandwidth, _BUT_ it is
possible to read/write/format Mac HD disks on a PC with an HD
drive.  I do it all the time with a product called Mac-in-Dos.
The company is Pacific Microelectronics, of Mountain View, CA.
I'm not affiliated with them, blah blah blah, just a satisfied
customer.  Just software, people.  No hardware mods necessary.

It's your permenant swap file ! 16Meg does seem rather large
though, go into
control panel, 386 enhanced, virtual memory and try reducing
it to 8 Meg
max. Windows will complain if this isn't big enough. 4 Meg is
usually big
enough, and if you have over 8Meg of RAM you can probably set
this to 0 (ie no
swap file)

Organization: Hewlett-Packard Co., Loveland, CO
Newsgroups: comp.sys.ibm.pc.misc

This isn't related to hardware performance, but in my experience Diamond's
technical support has been *terrible*.  I've had my Diamond Stealth card
several months and they still haven't provided bug-free drivers for
Windows 3.1 (640 X 480 X 256 and 640 X 480 X 32K).  The standard excuse 
has been, "We're waiting for new drivers from Binar."  And, instead of 
automatically sending updated drivers to customers who have reported 
problems, Diamond's response was, "No, we don't have enough resources
to do that.  But you can try calling us once a month or so."  Or I was 
welcome to browse their bulletin board--both at my (long distance) 
expense.

When version 1.0 of their drivers--the ones that came with my board--
failed to work correctly (trashed characters on the screen), I called 
and Diamond sent me version 1.1.  This fixed that problem, but some 
items wouldn't print properly on my LaserJet printer.  Although it took 
me a long time to identify a problem with printing being caused by a 
display driver, the second person I spoke with did ackowledge this as a 
known problem.  (The first simply wasted a week or so by sending me 
another disk of buggy drivers.)  As usual, the suggested strategy
was "try again later."

About a week ago I wrote them a letter reiterating my problems with
versions 1.0 and 1.1 and inquiring about newer drivers.  Yesterday I 
received another disk of drivers from them and--guess what?--they're 
yet another copy of version 1.1.  (Yes, I checked.  All the file dates 
are the same as before.)  It seems like whoever sent the disk didn't 
even bother to read past the first line in my letter (which was brief 
and clearly described which versions I already had tried).

I'm pissed.  My advice to anybody considering a Windows accelerator card 
is to buy anything but Diamond if you care about support.  I'm currently 
using the generic S3 drivers from Microsoft, but my measurements show 
that they're slower than the optimized (but unusable) drivers provided 
by Diamond.  Also, the ones I have don't support the 32K color mode.  But,
unlike Diamond's, at least they do work reliably.

That's true 99.99% of the time...but Infotel (also known as Zoom) is
selling really cheap V.32 modems...you can pick up an internal for
$169.  The catch?  You guessed it...these modems don't come with
V.42bis.  They're plain V.32 modems.  They're "upgradable" (you can
buy an add-on board that adds V.42bis), but I wouldn't consider the
purchase of any high-speed modem that doesn't include V.42bis as a
standard feature.

I am in the market for a PC. I don't want a Mac (I has a nice user interface
but the things are too slow by todays standards). I'm not sure on what to
buy but I have been looking around and obviously want to get the most for
my money. What I have in mind is the following:

486DX / 256 Mb cache
at least 8 Mb Ram
a 200 Mb HD + the usual 2 FD.
SVGA / 1 Mb-Vram
14 or 17" monitor (which??)

Now I've looked in the local magazines and found a lot of vendors that sell
these systems but for a big price difference. They range from 1700 to 2500+.
The Dell's are recommended but they are expensive - why? It's basically the
same system. Are the small local vendors reliable? Or is the adage 'You get
what you pay for' working here. What should I look out for? Any traps?

I have read the thread on 'the war is over'. Is it really. A friend suggested 
that I wait until Dec and but then because he thinks that the prices will
continue to drop. And they will drop even more when the 586 comes out - wait
till then. (I could wait until the fastest, most powerful system arrives, but
that wait it too long). I work on a Dec 5000/200 daily in software development
so I know something about hardware and software - but I've mostly looked at
the Workstation market and not the pc market.

If you have any mail order vendors that you'd reccommend, I'd be happy.
Any other comments would be welcomed.

I'm wondering if in order to take full advanatge of a local bus video card,
if the application has to recognize that the data path to the card is
32 bits as opposed to 16, 8 bits.  Applications I'm talking about are
normal VGA or SVGA type of DOS apps.  I'm aware that regardless of the width
of the data path, you'll get a local bus advantage because the speed of the
bus runs at processor speed.

The reason I ask is that I just recently purchased a noname 486-33 ET-4000 
Local Bus Motherboard and Video.  I'm really not seeing a big performance
boost over my old 386-40 with Orchid Pro IIs card.

Please email and I'll sum to the net if interest.

Comdex/Fall '92 will be November 16-20, and takes place in Las Vegas,
Nevada. Attendance will be about 120,000 people, so it will be difficult to
find a hotel room at this late date (actually, six months ago was already a

Comdex is primarily a PC hardware/software exposition, and consists of miles
and miles of various PC (and some mini) products on display. It is
theoretically intended for large purchasers.

Do you have the "spurious machine check" patch to trap.c installed?
I don't have any of this available anymore, but Bill ____ (gad, I forget
his name, but he was one of the AOS RT gurus) who was then of IBM's Palo
Alto division simply put a case statement in the main switch statement of
trap() in trap.c which caused the case of a machine check or machine check
in user mode (when no additional bits were set in the machine check status
register).

My RT used to crash several times a day until this change was made.

I have some problem with installing X11R4 on IBM PC RT AIX 2.1.2
The  source of X11R4 is from RICE university. I didn't compile the files
at all because the sources are just for PC RT . There are four directary 
for the X11R4: bin include lib man .

I put bin into /usr/bin/X11, and include , lib, man into /usr/lib/X11

Then I go to /usr/bin/X11 ,type " ./ Xibm "  .     The machine give such
information:


	Cann't open database" /usr/lib/X11/rgb "
	Creating socket : Addr is not surport by protocol family
        Server linked by Brantley on rosemary

I guess the problem is my RT version lower than X11R4 support version.
But I don't know how I am going to do next.

I know update PC RT is good way to solve it but the boss won't pay the 
money. Anyone who know how to solve it , Plaese give a anwer .

Thanks a lot

Subject: RT interrupt system
Keywords: MSD 2.6, parallel devices
Date: 1 Oct 92 18:50:23 GMT
Organization: College of Engineering, University of Cincinnati

Our RT's seem to make good print servers...  The parallel port on
the megapel card works well.

Naturally, we'd like to be able to use them to drive more than one
printer - without going to one parallel, and multiple serial.
Multiple parallel is the goal.

I gather under AIX, one can simply grab an XT serial/parallel card,
and go - or so some of our old AIX doc suggests.

Under MSD 2.6, it appears there is some vestigial support for a second
parallel device, but it's not quite all there.  Noteably, the
"MASTER.ca" configuration file does not know about the possibility
of a second parallel port, and /dev/MAKEDEV was misinformed about the
proper minor number for a second port.  (It wanted to use 0,1,2, while
the limited driver support clearly expects 0,8,16).

I've got a kludgy driver hacked together, that just ignores printer
interrupts, streams info at the printer whether it's ready
for it or not - but slowly, in hope of not overrunning.  Blech.  It
writes to the printer ok, so I'm reasonably certain I have the right
memory-mapped region for sending data located, and the user-kernel
interface cleared up.

The problem is, I want to use the interrupts, but I'm just not getting
natural interrupts for the second card; There's a routine in the kernel
which I believe should only be executed in response to an interrupt -
but when it runs, it will find that the 8259a in question doesn't know what
caused the interrupt - kernel messages about "spurious interrupts" come to
the console.  The "something interrupted me" bit on the 8259a in
question, just isn't getting set.  I tried ignoring said bit, and that
gets about five characters printed, before it just dies.  I'll look
into it further, later - I wanted to seek some input before continuing.

Also, if I interchange the I/O addresses of /dev/lp0 and /dev/lp1,
the megapel parallel continues to work, but the XT doesn't start
to.  So it doesn't entirely seem to be something about the kernel,
at this point.

I may end up adding some printer-specific hacks, to the general "which
interrupt to service" routine, to poll the printer device - but would, of
course, prefer to keep the code cleaner than that.

The XT card I'm using appears to function under MS-DOS, although I'm
not sure if DOS polls off the timer interrupt, or functions off an
actual printer interrupt ("Can you take more?  Ok, here's more" vs
"I'll wait until you tell me you're ready")

I currently have both printers on IRQ 7.   The source looks like
it was -intended- to handle having multiple printers on the same irq.
Putting the XT card on IRQ 5, I don't even get "spurious interrupts".

That was long winded.

Anyone have any ideas?  Is there anyone out there, who can give me a
breakdown of the RT interrupt system?  What might be the relationship
between the 8259 handled interrupts, and the "level N interrupts",
which appear to pass control to the 8259's sometimes?
