The NEC V20/30 are developments of the 8088/6 CPU, that normally drop in
to the intel socket - at least I have had no problems.  The V20 for the
8088, and the V30 for the 8086.  They execute most instructions faster,
for the same clock rate, though string operations are slower.  They also
include all the instructions added to the 80186 and 80286 Real mode, as
well as a few extra & an 8080 emulation mode.  

Sony are a second source for the V20/30.  There are no hardware restrictions,
so far as I know on replacing the 8088/6 with a V20/30, but V20/30 based
systems often have a 50% duty cycle clock whereas the 8088/6 requires a 33%
clock - so cannnot be used.

The NEC (SONY) parts are the only CPU upgrades available, unless you buy
a 'turbo' board where a better spec CPU operates but passes keyboard, screen
and disk data through your original PC & CPU.  These used to be really 
popular so if they are no longer made you could possibly pick up a second
hand one.

Hi Netland!

The subject tells it all - does any one of you know where I can get the
low-level drivers for the Adapter-Independent version of Lantastic 4.1
for the following ethernet-cards:

	.) Intel EtherExpress
	.) BICC Isolan 4110

THe story is this: I started off with the Zero-Slot Version with the parallel
port drivers. It works great and is the only - as far as I know - really usable 
fully blown peer-to-peer network that runs without boards. But now I received
those adapters and - obviously - would like to switch the transport media.

Actually I have some drivers - like for the Artisoft, 3COM and NOvell cards,
but not for those I received.

So, if some kind soul could e-mail me these drivers I would be very thankful.
Also a ftp-adress or BBS-number, where I could download these things would
be sufficient. Or does anybody know how to tweak an ordinary net-bios driver
to work together with Lantastic 4.1 AI ?

	Just put a second B connector in parrallel with the one that is there.
Remember, the B connector is the one closer to the controller. The only twists
in the cable are between the A and B connectors.

I am considering upgrading my system and was wondering the following
(especially after the recent spate of articles about the SpeedSTAR
24X, etc...):

Does an ISA system with local bus slots (one for VGA and one for disk)
have as great an impact on system performance as claimed by the
manufacturers?  Will a system with a local bus and a S3 card
outperform a system like a G2000 with an ATI Ultra card (video only,
of course, assuming all else is equal)?

The 486 has some additional instructions, and the 486DX has
an onboard math co-processor, if that helps.

Hi folks,

I have an old 286 (yes, I'm saving up for a 486, but I'm not quite
there yet...) motherboard that has worked very reliably for me, even
using Windows 3.1.  At any rate, I am in desperate need for more drive
space, so I've decided to get a 200MB IDE drive.  Predictably enough,
though, my 286 BIOS supports no such drive.  The largest drive in the
BIOS is about 100MB.

Has anyone had experience with BIOS upgrade outfits?  I know many
are available, but the one place I called wanted $69 for it!  At that
price, I may as well get a new motherboard!  Any suggestions would
be appreciated.  The chip set in my machine is by Suntac.

The other option is for me to find someone who can burn a modified
copy of my existing BIOS with a hard drive parameter set for my
new drive.  Any comments on this?  Anyone out there have the equipment
to do it easily?

My apologies for discussing such outdated equipment, but I am a
poor student...

Thanks.  Please reply by EMAIL, since I rarely have time to sift
through this newsgroup.

I believe that the BIOS, while many of them are written by AMI, are specific
to the chipset used on your motherboard. AMI just enables what options are
supported on your board and does not have to have specific code for every
machine type.
 
I'm sure I will be corrected if I'm wrong.

I don't know if this makes a difference, but does the motherboard
documentation say that the larger SIMMs are supported?  I've got a Micronics
386DX-33 motherboard in my Gateway 2000 and although 4 MB SIMMs were on
the market at that time, the documentation only mentions 256K and 1 MB SIMMs
and the Gateway folks themselves said my memory capacity is 16 MB.  Not
wanting to take any chances, I have stuck with 1 MB SIMMs when upgrading
despite the fact that I could have got a 4 MB SIMM for less money.  Can
someone enlighten me on this?

Thanks.

Date: 12 Aug 92 18:03:02 GMT
Organization: Hewlett-Packard, Santa Clara, CA

I/O speed is ALWAYS 8Mhz regardless of the CPU. That's how they can maintain
the compatability across the x86 Intel platform. Since each I/O cycle takes
from 3-4 BCLK (8MHz), the proper access time of DRAMS is much less than 127ns.
The possible difference between computers is in the I/O wait state, with
the fastest running with no wait state, hence 3 BCLK for each I/O. So if
the memory board inyour 286-8 is running with 1 wait state ( the system
inserts 1 extra clock in 1 I/O bus cycle), and your new system has no wait
state I/O bus, the memry can lock up. Changing to faster DRAMs may or may not
help since the timing on the memory board may be slow to catch up with the bus.
So please check the memory board manual for thing like wait state.

People have long been agry about the dual-monitor setups because they
force the 16-bit VGA's into 8-bit mode when an 8-bit mono card is in
use. There are no 16-bit mono or hercules cards available, but I have
been wondering about using an OAK SVGA-card as a second card,
configuring it to emulate (DIP) an MDA-card. As the card is 16-bits, shouldn't
they then work well together?

The solution seems too easy to be true, and I haven't spent money on
testing, as nobody knows whether it would work or not.

Yes get a 16 bit SCSI controller or move the 8 bit one to Exxx.

The ISA bus supports 16 bit read/write in 128k chunks. This
means that A000-C000 and C000-E000 and E000-FFFF are the groups.
Since it is the ROM that sits at C000 you shoul shadow this into
16 bit RAM and not worry that the ROM is in 16 bit mode. The 
card is probably using 16 bit I/O for the Video RAM between A000
and BFFF anyway.
