It's more like this. 

On an 8088, an attempt to access any address in the FFFF segment would wrap
around to low ram (FFFF:0000-FFFF:000F was the top 16 bytes of RAM, the 
rest of the segment was at 0000:0000-0000:FFF0).

On the 286, the accesses *didn't* wrap, they just went on to the first
64k-16 of RAM above the 1 meg mark. 

Apparently so major applications programs *depended* on the wraparound.
So if the wrap around couldn't be duplicated, they wouldn't run on the
AT, and nobody would buy it. But at the same time, The AT needed to
be able to run protected mode OSes like Xenix. Which required that
the addresses *not* wrap.

The obvious solution was to put in hardware allowing software selection
of the hardware for the "wrap kludge". 

I suspect it was tied to the keyboard controller because it was the 
only "free" toggle. Or at least the easiest one to deal with. Why
add a chip when you have an unused portion of one that'll do the same
thing?

The slowness *only* matters if you are toggling modes frequently. Which
*shouldn't* be happening. The old software that required the kludge
is gone by now, so the kludge can be disabled and *left* disabled.

I just spok to Gateway 2000 today, and they told me that the 
Ultra Graphics New Generation that they are going to ship
SUPPORTS a RAMDAC chip for 24 bit color, but that you have to 
purchase it through ATI.  Gateway knows nothing else about it.

So, those specifications form CI$ are somewhat misleading..

The 24X card is not what would be considered a "downgrade". Most 
benchmarks support that the 24X card is better than the Stealth
in most cases. There will be OS/2 support for the 24X and Stealth
as soon as IBM releases the 32 bit graphics engine. Anyone that
wishes to develop drivers for the 24X card for freeware Unix Operating
Systems, under the current requirement, is asked to sign a non-disclosure
agreement with Diamond. There was a post earlier stating that several
of the freeware unix developers were not going to support the 24X card.
It may be a better approach to design drivers under Unix that support
VESA video modes. Most of the Diamond cards and others support the VESA
video standard. 

The 24X card is quicker on some operations than the Stealth. There are
less addressing problems with I/O ports on the 24X card than there are
with the Stealth. S3 chips conflict with COM4. There is a 32 bit version
of the S3 chip and the ET4000 chip in the works.

Subject: adding a 3.5-inch drive (outcome)
Organization: Computing Services, Warwick University, UK
Date: Mon, 7 Sep 1992 16:46:12 GMT

A few weeks ago I asked about adding a 3.5-inch disc drive to my
mother's 286-based computer.  I thought people might be interested
in what she eventually did.

She took the computer to the local computer shop and the staff there
added a new external disc drive and fitted a new cable.  The new
drive is a 1.44MB model and it works but the version of MS-DOS 
(3.20) she uses can't manage 1.44MB floppy discs, only 720KB ones.
The external drive is the B: drive so the cable has to come out of
the case and then go back in the case to the A: drive.

The only problem seems to be that the old internal A: drive sometimes doesn't
report that the disc in it has been changed.  We told MS-DOS using
DRIVPARM in CONFIG.SYS that the drive doesn't have a change line
and the problem has gone away.  I think this is due to the cable being
so long.

Hi 
I am going grey(er) trying to install a Maxoptics Tahiti 2 (eraseable 
optical drive) and  SCSI adaptors. I bought it from a Uk company named 
Magstore but it says Mega Box on the front. Here is the problem

First they supplied a BusTek BT-542B, I followed instructions - disabled the 
BIOS and floppy controller, connected it all up and the card just sits there 
flashing its led 3 times - same with another card. (Oh by the way I can only 
manually eject the cartridge by disconnecting the cable from the adaptor 
card and removing the terminator).

They supplied an Adaptek 1542B - same procedure except that it would only 
work if the terminator plug was removed from the drive. Installed ASPI4DOS 
and the Corel software drivers - all seemed to work except that after a few 
writes I get lots of Abort,Retry,Fail messages and I cannot read from the 
drive. It formats ok (or at least seems to) but you just can't use it. The 
Corel DIAGS program will run ok a little then hang on seek or read tests. 
The most frequent error number is 0x030B.

I borrowed a Corel LS2000 8bit adaptor and connected it up, installed the 
Corel ASPI driver, reinstalled the Corel drivers and it all works fine. 
Transferred lots of files seemingly totally reliable.

I haven't mentioned which PC because I have tried 3 different ones with 
exactly the same results. A Elonex 386/25B (OPti chipset, Phoenix bios, 2 
IDE drives 4M) an elonex 286 (G2 chipset, Phoenix bios, 1MFM drive, 1M) and 
a Dell 310 (C&T chipset, Phoenix bios, ESDI drive (CDC), 4M). The only thing 
in common is the Phoenix bios.

I thought it might be the cable so I borrowed another drive and cable and 
daisy chained the Tahiti with a Panasonic 9010 all ok.

It looks as if I will have to abandon a 16bit card and stick with a Corel 8-
bit. 

Anyone any ideas before I send all the boards back? The poor guy at Magstore 
tech support has been very helpful but we are getting stuck here.

I am attempting to modify some serial i/o code so that I could access IRQ2
(actualy 9, but they're supposed to be mapped)

The code itself works just fine, I can put in the numbers for any normal
IRQ, 3-7.  I have apparently set the 8259 correctly, since the inportb and
outportb to port 0xa0+1 (the second 8259 mask) show changes to the 
interrupt mask.

However, when I use the _dos_setvect(), (I think I redirected to 0x71)
and then run the code, interrupts are never generated.  I know I can
tiggle the UART bits, but I cannot get an interrupt generated when data
comes in, and I can't cause interrupt to send out characters.  Any
ideas/pointers to books/help?

There's no such thing as 4 MB SIPPS...is there?  My middle-aged machine (a
386DX/20) uses SIPPS.  I haven't heard of anything larger than 1 MB.  In fact,
larger capacity would enable me to nurse a couple more good years out of my PC,
since my usage does not depend on screaming speed...just upgradability.

Oh, and if there are 4 MB SIPPS, where are they?  I'd also be on the phone with
the motherboard manufacturer pronto.

Hi all. I have not used a PC in years so I could use some help selecting

   + 150M internal drive or better
   + Mono or Greyscale active matrix display

I am not sure if you find active matrix in non-color systems. All I saw
at CompUSA was active color.

I will be running UNIX on this and, eventually, NeXTSTEP 486. I would
like the system to support the following add ons:

   + High speed modem (v.42bis, external or internal)
   + Ethernet adapter
   + External drive

I think I could use at least 300M of disk. I know HP has some really small
drives now. have any notebook manufacturers started using them? 

Thanks in advance,

From what I understand, the SCSI interface allows multiple computers controlling
the same SCSI peripheral. A switch box is not needed. I have never tried it myself

Sounds more like a software problem to me. As far as I know (which may or
may not be very far - your milage may vary) the only string to which a
Hayes compatible modem will respond is +++, which is typically followed
by ATH or some such. I also seem to recall that there is some degree of
delay between the "hey you!" string (+++) and the command string.

well, lets take a look here:

This looks very much like the speeds for your isa bus.
the first one is provided for compatibility with the original

a hitch to 11-12mhz (i run my ISA bus at this speed with
no problems, unless faster is a problem :) ). The ISA
bus *can* do 16mhz, i have done it, without problems, except
that the data would get to my video card faster than it could
be drawn (its a VERY slow card) causing parts of the screen to
be left out.

Usually ISA busses are preconfigured/defaulted at ~8mhz. Running
it faster (like about 12mhz) doesn't normally cause problems
with today's hardware. I would try out both 12mhz and 16mhz,
and see which works the best, faster being preferred, just
dont blame me if that 10 year old serial port blows up.

I just ordered a 16550 for my computer..  I got mine from B.G. Micro,
they offered the 16550 plus the 1488 & 1489 for $13.50 + 3.25 S&H.
I assume the 1488 & 1489 are just the support chips needed to add a serial
port to some cards,  I didn't need mine though, I was just replacing
a 16450.

You can reach them at:
B.G. Micro
P.O. Box 280298
Dallas, TX 75228
(214) 271-5546

BTW - I'm not affiliated w/ B.G. at all, and yes it was the newest chip.
Mine had both 16550AFN, and PC16550 printed on it.
