Tseng Labs ET4000 Databook - summary
mar...@minster.york.ac.uk
Last week I asked the net where I might obtain low-level programming
information for the Tseng Labs ET4000. Many thanks to everyone who sent
me mail. Several people asked to get the information I collected,
so I am summarizing to the net.
A special thanks to those people who offered to photocopy manuals
they have, or to send me their ``spare copy''. I haven't included their
mail here, since I'm sure they don't want to be inundated by requests
from the net, but their offers were greatly appreciated!
I got a copy of the Tseng databook from Orchid by phoning their UK
number - given in the first respopnse below. This cost 20 pounds
(inc P&P), but seemed most convenient at the time. I now discover that
even this is still rather coy about the details of the contiguous
1Mb linear memory organization, which is the thing I'm most interested in!
(Does anyone know if this works on ISA cards, or know any more details
about where the 1Mbytes is mapped, etc? Also what the ***** is the
``PEL add/Dat Wd'' register - at i/o port 3CB - I can't find any mention of
it, except in a table on page 96!!!! Ditto the Microseq Mode, and Microseq
Reset registers - GDC registers 0x0d and 0x0e - on page 98!)
Apart from these problems the databook exists, and is quite useful.

[Tseng UK did not understand the part number given here, but the ET4000 databook
is part of their documentation for the ProDesigner II. I gather that the ET3000
databook is similarly available in the documentation for the ProDesigner.
By the way, in this case $25 = 20 pounds - Martin]

Diamond told me to look at
Ferraro, The Advanced Programmers Guide to EGA/VGA. They said the
2nd edition had info on the T4K chipset. HAven't seen the book so I
don't kow if it will meet your needs/

[ I have Ferraro's book (2nd Ed.), and it does give some Tseng details, such as
the code for bank switching. However it is rather hazy about other details,
such as the flat memory mode, and programming Super VGA modes - Martin]

I got my Tseng ET4000 Data Book from the dealer I bought my 386 from. Like
you, I saw the reference in the manual that came with the card. I had to
place an order for the book from the dealer---cost me A$60. The book is
pretty comprehensive but I haven't gotten the chance to use it lately.
There are 2 addresses at the backcover:

Hello Martin,
I own a ET4000 manual. I bought it from the a german TSENG distributor
which adress was on the drivers disk coming with my MEGA EVA card.
I don't have the adress with me right now, but there must be also
a TSENG distrubutor in GB selling the manual.
It costs around 100DM but don't expect too much. My book came with
the pages mixed up, some wire plans at the beginning of the manual
(how a VGA card usually is build up---memory and that stuff) is
unreadable because its very small.
50% of the manual covers the standard VGA registers and BIOS calls
and the rest is for the TL extensions (registers and extended VGA modes).
It's written like other data sheets and it still takes some time
to understand it.
Sincerily,

STB systems's PowerGraphVGA uses the ET4000 chipset and I was able to get
the docs for th or
P.O Box 850957
Richardson, TX 75085
or
214-234-8750 (Technical Support)
When I called, I just asked for the technical documentation for the PowerGraph
VGA, they asked for my address and name and sent it over within a week.

I wrote to STB Tech Support and they sent me the latest BIOS and
the tech ref for the chip. FREE to Australia. $12 postage.
I don't know if they'll do it for free as the chip gets more
popular, though.

I got a copy from a friend at Sigma Designs, a VGA manufacturer who uses
the chip. STB, a competitor of theirs, is generally friendlier to most
developers, though. Orchid also makes a T4000 board, but I have not dealt
with them personnaly.
All three companies are in San Jose, CA (information 408-555-1212). Actually,
I think Orchid might be in Fremont (a few miles north of SJ), which is in
area code 415 rather than 408.

I got a copy of the ET3000 manual from the Orchid folks (they used that chip
in their ProDesigner VGA). Since the ProDesigner II uses the ET4000,
they might have the manual for that, too. I'm afraid I don't have the
address handy, but I could be compelled to look it up (at home).
One thing: if it is anything like the ET3000 manual, beware of typos.
