 I've noticed that most new 486SX PC clones offer VGA with local bus
hardware for CPU/VGA-card communication.

 If one decides to stick to Windows and gets a good Windows/VESA
driver with the computer, will a VESA solution generally be much
faster than a system with an ISA bus operating at a higher speed
than 8 MHz? (Many clones feature an AT bus speed option in the
BIOS setup menu.)

 Also, if anyone could explain the major differences between
the two solutions, I would really appreciate it. I've used some
computers over the years ever since I bought an 8-bit Atari back
in 1983. In that computer, the CPU and the graphics chips shared
the same memory with a noticeable CPU slow down during graphics
DMA. It appears to me that a PC/ISA computer is not slowed down
during video memory scan, which isn't too surprising since VGA
cards seem to have their own memory. On the other hand, CPU access
to VGA video RAM is noticeably slow.

 Now that VESA is introduced, what will we end up with? Will we get
faster (memory mapped) CPU access to video RAM with the slow-down
caused by a shared bus as a result?

 Thanks in advance for any hints on this.

 Best regards,
 Anders Skelander

I posted a note earlier on problems with the HPLJ4 printing full
page graphics such as GIFs or BMPs. Several people responded and
suggested at least 4MB of memory is needed to do this. I added a
4MB simm giving me a total of 6MB since the 4MB simm was not that
much more than a 2MB simm. I can now print any file at full page size
and it really looks good!

I also got my screen fonts from HP and now my MS Word screens look

Oh, please, if you don't have REAL data don't pretend as if you do.
A 486DX25 runs at more than 50% the speed of a 486DX50 in identical
systems.  Where did you get the idea that a DX2-50 can ever drop
to 40% the performance of a DX50 --- less than its single-clocked

I don't have exact data on hand, but it's more like 65-90% of a DX50.

I've got the gateway machine (66DX2 Vesa) and it only takes 4MB or 16MB
simms, or some combination of the two. However, it can accept at most 2 of
the 16MB simms built using the old parts. (The limitation was supposed to be
because of the extra capacitance of these parts)

I did something similar - I ordered 16MB and requested it on 1 simm. I got
the system on time, but it was someone elses order! Since it was the same

I am currently looking for a tape backup that connects to the parallel

Trakker (250 MB).  

Seems that people have encountered reliability problems (re articles from
this group) with the Trakker but I have yet to see any comments on the
Backpack.  

The cost of Backpack (from mail order houses) seem to be slightly higher, 
and from info received from the respective companies, Backpack is rated
slightly faster (9 mb/min vs 8 mb/min).

MicroSolutions also makes hard drives and floppies that they claim can
be daisy chained together (are they SCCI devices?).

Are there any comments as to which is better?

True, it does have two bays, one is taken by the 1.44 3.5" floppy, the other 
by the 60.  That is why he will have to replace the 60.  There is no way he

You need to purchase a floppy or FD/HD controller for an PC or XT.
The board needs to have a ROM on it.  The ROM has an assigned
starting address at which the code will "mesh" with the the ROM BIOS
on the motherboard.  If all goes well, all you need to do is start
using the floppy drive.  It is suggested though that you have the
latest version of MS-DOS loaded (= 5.0).  

Someone may want to clarify this procedure and if so that's fine,
especially since my own attempt failed.  I suspect that there may be
some problem with compatibility of the m/b rom and the board's rom.
Nevertheless the user can still use 720K floppies.

This kind of function is present only if your chipset supports it.
The BIOS 'Advanced Chipset Setup' differs for different chipsets/

Not all AMI BIOSes are created equal.
