I was wondering if anybody could tell me what the jumpers on this card do.
Both floppies running off this board died simultaniously--they spin up,
and then return "Drive not ready"--and I would like to avoid reformatting
the HD by just diabling the floppy controller, keeping the HD on the card,
and getting a new discrete FD controller.

The card in question is the standard full-length integrated 16-bit controller
card shipped with the old IBM ATs.  There are three sets of jumpers, and
the stickers affixed to it note "X+ECO1611", "6480111", and "RR-37859".

If somebody could just tell me how to disable the FD contrller half, I would be
very grateful.

Thanks,
Dave

I ordered a Gateways 4DX-33V on October 21 and was promised a 3-4 week
delivery. It is now past the 11th week after I ordered the system and it 
has not been built.

I have been working with customer service to get the computer shipped. 
(after wasting hours of time dialing, redialing and being put on hold)
Customer service is polite but powerless to get it shipped.

I ordered the system with many options, a fax/modem, soundcard, tape backup
and a CD-rom. The main problem appears that not all of the parts are in 
stock at the same time. At various times they have been out of the tape backup,
motherboard, the sound card, and the CD-ROM. Since Gateway does not seem to
set aside parts to put in a system, a system like the one I ordered can take
a long time to get built. 

They also will not ship parts to you later. They allow you to cancel parts and
then charge more to order them separately.

Summary: Regarding the PC Magazine reiews

Organization: Iowa State University, Ames IA
Date: Sun, 10 Jan 1993 21:58:37 GMT

With the various discussion about the PC Magazine reviews, I looked a
bit more closely at the company/product profiles. Specifically, I was
looking for differences between the Tri-Star and Gateway machines which
might cause a difference in performance. [An aside here. The Gateway
2000 uses a Western Digital hard drive while Tri-Star use a Maxtor. 
This might explain part of the difference.]

When examining the cache, I noted that the Tri-Star has a 256K cache,
while the Gateway uses a 64K SRAM cache. When I started looking at
other vendors, I noticed that many had a cache of a given size while
others used an SRAM cache.

I'm a bit curious. I know that the primary requirement for a memory cache
is that its rated speed must be less than the recipricol of the clock
speed (e.g., 25MHz needs 40ns memory,). I wasn't aware that any kind of
memory except for static RAM (SRAM) was capable of this kind of performance.

So, here's the question. Is there any differene between a cache using SRAM
or one which doesn't (assuming identical size and design otherwise)?

I've narrowed the choice of what system I will buy to two and now wish
to make a final decision between the Gateway 2000 486DX2-66V and the
Zeos 486DX2-66 VESA Local Bus System.  The systems seem comparable in
terms of performance, features and cost in terms of my needs and
budget.  I will be buying only a system unit (i.e. motherboard,
processor, memory, etc. within a tower case) and hard disk but no
monitor nor graphics card from one of these two vendors.

I want to base my final decision on the overall quality of systems put
together by the two vendors and in particular, how well these two
particular machines are built, and in addition take into account the
reputation of each vendor in terms of service and support.

I would appreciate any praise, grief, or other comments from those who
have previously made their choice.  I plan to summerize that which I
receive together with a promised summary of a previous post early next
week.

I know that the price of the Tandy is not as good as, say, a Gateway

MPC stuff work better because it has been configured and tested by  
the company? 

The 105 Mb hard drive seems a little small - will it limit the number

Has Tandy cut some serious corners that are not readily apparent? 

Is the system a good bet for home use?

Sorry, but if the Amiga is a games machine, then what is the PC? It has
far more games than any other personal computer.
 
There are a few very good games for Sun workstations, and they doesn't
make it a games machine. They only show the computer's POWER to do stuff
like that. Things that require fast machines, fast image display, and
of course, good audio quality.
 
What's the deal with the MSDOS machines? every program that runs on the

Yes, the increase in the bus speed will increase the performance of
disk I/0, video etc. But for a truoble free operation at any speed
higher than 8Mhz (which is the standard ISA bus speed), you must also
need good quality hd/fd, video and other add on cards. All of your
cards should be rated and tested at the specified speed. Most cards
normally rated for 8mhz, but there are cards out there which are rated
at higher speed. Now, if you run a card beyond its rated capacity,
then it may or may not run. But most of the time most newer cards will
run at 10Mhz without any problems. The 12.5Mhz is little optimistic,
but if you are able to run at that speed then test throughly with
intensive disk I/O operations under different OS. I found that, 12.5
Mhz works fine as long as you are within native DOS, but it makes
troubles under Windows (normally the system hangup during disk I/O
operation). It also creats problems under OS/2 at 12.5Mhz. If you are
running X under Linux then you have to set the bus speed very close to
8Mhz (I was completely unable to run X under linux at 10 or 12.5Mhz)

So, the bus speed of 10Mhz is probably the best choice for DOS, Windows 
etc. If you want 12.5Mhz then, test throughly before settle down.

Theres a good reason for it too, actually. The big bottleneck
in tape backup is the actual writing to the tape. The fewer bits 
you can write to the tape the faster your job gets done. So not 
only does the tape hold more, the transfer rate goes up quite a 
bit.

We bought a Maynard 4mm DAT drive just before the new compression 
drives came out *sigh*...

I have also seen this article and have a few questions:

1. What is the Opti Local Bus Slot (VESA? VL-Bus?)

2. I see all the motherboards use 70nS RAM, how can this be??

3. If the choice were between a DX33 and a DX2-50, which is the best buy

4. Would I need a chip cooler (fan) and if so where can I get one in the UK?

5. The prices for the board with no RAM are as follows (in pounds sterling)

   SX25     244
   DX33     374
   DX2-50   404
   DX2-66   454

  How do these compare stateside? (I think the exchange rate is about 
  $1.55 = 1 pound)

6. Is the 486DX2-66 a reliable part?

7. Is the AMI bios, SIS chipset a good one? I have heard of problems
   with various 486 boards when used with Adaptec 1542s and SBPros,
   both of which I have!

8. Has anyone bought one?

Please EMail or post soon as I have money burning a hole in my pocket,

Yes, you are correct. GIF files are not compressed by popular backup

I presently have two IDE HD's connected to my system through a multi

disk space, and would like to add another drive. I don't anticipate
going beyond 4 total HDs in the forseable future, and would prefer
to continue with IDE drives instead of also investing in a SCSI 
controller and SCSI drives.

1.   In order to add IDE drive #3, could I just buy another generic IDE 
     controller (which supports 2 drives max) and add another drive, or
     would I have to disable the IDE controller on my multtifunction card
     and buy one of those 4-drive IDE controllers?  

2.   How would I set the drive types for drives #3 and #4 (since my AMI BIOS'
     setup screen seems to only recognize 2 drives.)

3.   In a 4 IDE drive configuration, is one drive the master and up to three 
     drives the slaves, or are the drives configured as a pair of master-slave
     pairs?
