   Actually, I want to buy both.
   And I have only one drive bay to use.
   Will I have to remove one of floppy drives, or have to get
   one of these external, of there are some better options?

   I would greatly appreciate any advice.

The July PC Sources has reviews of 14 different 9600b modems.  While they 
didn't review fax modems, I did find the reviews helpful.  After the reviews 
they listed a number (>20) of modems and their features, including fax 
capability and chipset (e.g., Rockwell, AT&T, etc).

I wanted the fastest, 'cause I'm that way.  I basically looked for most 
bang/buck.  I'll be running it under Linux so I didn't really care about
DOS software or free time on CompuDowProdGen*.  I was planning to go with 
external cause I heard that most internals don't come with the 16550 UART 
(appearently a MUST if you're running in a multitasking environment at that 
speed).  

I finally decided on an internal modem from Lightning Communications.
It's 14.4 Data/Fax, V.32bis and V.17 fax (also Grp 3), MNP2-4, V.42bis w/MNP 5.
It uses the Rockwell chipset, which seems to be most common.  Here was the 
kicker: It has a 16550AFV chip (has FIFO) comes with both data and fax 
software (don't know how good it is) and it was a cool $279 ( + 7.75% tax, 
free ground shipping).  I haven't got it yet as they're currently back ordered 
by a week.  But they do have the somewhat standard 30 no risk deal.  After 
Aug 8, they'll have an external model for about $40 more.

If you want to check it out they're number is (714) 457-8001, support BBS
is (714) 457-9429.  They're in CA.  

Good luck,

Reply-To: pp@info.win.tue.nl

Hi fellow netters,

I'm currently working on a Philips pc-xt and have to replace the
harddisk. The original harddisk has a 50 pin connector. I have a spare
(same harddisk type, different interface) that has two connectors,
one 34-pin and a 20-pin connector. What I would like to know is if it's
possible to use the "two-connector" disk in the pc (that has a
on-motherboard controller with a 50 pin connector).

Is there a way to connect this "two-connector" harddisk to the pc with
a working harddisk as a result ? I tried exchanging the harddisk
pc-boards (NOT the controllers, but the pc-boards mounted on the
harddisk!), but that didn't work. The only difference (apart from the
connectors) I could see is a copper contact/spring that touches the
spindle of the harddisk.  I don't know what this contact/spring does.
It sure is not a mechanical function....

Can anybodey make any sense of this....

Thanks in advance for your reply.

		Peter.

/I though the 32 bit "flat" address space worked quicker because the processor

/to do a pointer.

To quote Bart Simpson,   "Au Contraire, Mon Frere"
  In Real Mode, it is a simple matter of shifting a word left 4 bits and
adding the offset.  In protected mode, the segmant is a _HANDLE_ which points
into a (memory resident) table of segment descriptors.  The segment descriptor
then contains the base address of the segment (incurring one memory fetch just
to get the address of the desired memory fetch).  If PAGING is active, a second
level lookup is required (hence a second memory fetch) and finally, the offset
is added.

   How, you might ask, does protected mode run at all with all this overhead?
The 386 & 486 have segment discriptor shadow registers which are loaded the
first time a segment registor is loaded.  This eliminates the first fetch.  I'm
not clear about the paging; however, I suspect that most OS'es don't use it
(i.e. the Hardware version) and perform there own Virtual Memory operations
when a page fault Exception occurs.

   For more details about the 486 wonderchip and what it could do if we'd
let it, buy the book "80486 Programming" from the Computer Book Club...

If you buy an OEM product, like a hard disk, then no, you shouldn't
expect to get anything but the disk drive.  OEMS save money by
buying products without all the redundant packaging and documentation
that you would expect when you buy something retail.

Conversely, if you've bought a "hard disk kit" intended for an
end-user, you should expect to get a manual with it.

A monitor is a decidedly bad place to try and save money.  The monitor
is the part of the computer that you will have to look at for several
hours each day; it pays to spend a little extra to get a quality one.

If you can't afford a quality 17" monitor, then either wait until you
have more money, or get a quality 15" or 16" monitor.  Don't try to
save money by buying a low-end monitor, because you'll be very unhappy
with it in a month or so.

Set the quantum as primary and the maxtor as secondary. Jumper the
master and slave jumpers on the Quantum. You shouldn't need 
a slave jumper on the Maxtor. If that doesn't work, jumper the
Maxtor as a slave.

Of course this is a good point. The primary interest of Intel (and others..)
is to make money, and eventually the make it by selling chips.
BUT in this particular case I am not sure if this is the only reason.
To my knowledge the have delayed the presentation of the P5 several
times (even from an engineering point of view) and it is unlikely 
that the will make architectural modifications within the extra time.
So what caused them to delay *presentation* at conferences if not
real problems with making the chip? If I had to speak about something
I'm not sure I can actually implement I'd feel a bit uneasy , too.
Especially if on the same conference the product of the competitors
are already selling ...

A guy on CompuServe who seems to know his stuff really well says
that the clock will be different as well as the RAMDAC.  Also,
I'd guess the BIOS would have to be different too.  So that's
three chips.  I'm not sure which are socketed and if the other
chips on the board depend on properties of these chips.
My guess is no, you could not upgrade, but of course, I don't
know.

Lo and behold just as I've given up on Gateway 2000 and their
Telepath modem I find a COD package is waiting for me at FedEx.

So now the problem is, should I take the plunge and go pay for it
and pick it up.  To answer this I need the answers to a few questions.

1.) Which UART does it have?  Since I'll be using it with either
	Coherent or Linux I >*REALLY*< need a 16550 or SOME kind
	of buffering of the interupts.

2.) Does the modem support re-trains to a lower and/or
	higher bps as phone lines conditions change?


If someone with one of the 'new' Telepaths could answer either
of these questions it would be greatly apreciated.    :)

I have a system with a Maxtor 7120 HD.  The problem I have is that the system 
only seems to recognize 43MB.  IDEINFO reports 2995 cyl., 5 heads, 17 sec. for
 124 MB.  The system has AMI bios and I set the disk type to 47 with the above
settings and chkdsk only reports 43MB.  The system was delivered with dos 5.0 and
windows installed and the company(garage operation actually) insists there is 120MB present on the HD.  How do I get at it?  
I have tried:
another IDE controller.
a CONNER HD, 120 MB.
In every combination I can only get 43MB.  FDISK reports no space avail. for
an ext. partition.  On one test, I did manage to fool QAPLUS into recognizing
the 2995 cyl and it passed all tests. (I had QAPLUS update bios with "no HD",
reboot with bios checksum error, use AMI setup to set HD to 2995 cyl etc., boot
from floppy to run tests).

With the different IDE controller and CONNER drive giving me 43MB, I'm starting
to suspect the bios.  The CONNER drive was checked in another system and has
120MB.  

Two different tech have told me that the disk information database report that
the maxtor should have 1024 cyl, 14, heads, 17 sec, which contradicts IDEINFO.
Can anyone confirm that?

All help greatly appreciated.

So much for theory #1 - Now for theory #2:
Electromagnetic Interference (EMF) - I once took an introductory course in
AutoCAD at our local high school.  There was an entire row of identical
SVGA monitors - and mine was the only one with a noticible flicker.  I
talked to the instructor who informed me that it wasn't the monitor, but
the location. They had swapped several monitors into that workstation with
the same result. Turned out there was a "noisy" electric circuit in the
wall behind that workstation - all the other monitors were just far enough
away for the effect to disappear.

Florescent lights are the culprit more often, but it could also be EMF.

	Seems like 1/4 or 1/2 w should be fine. Since its only a momentary

I guess for safety sake, make it 1/2 watts resistors.
	The values themselves I don't know - I suggest someone open
their analog joysick and measure the resistance in each direction.. since
there's nothing but directional pots in there, its fairly simple to get
