Thank You very much.
But will it work on 8Bit ISA card?

Basically the bios wil communicate with the system Board and graphical processor without looking at the 16 bit part. Even moest 16 bit cards wil work without Jake in any 8 bit slot. So I don't think it will be a problem at all.

I have such a card, too - here's the dump from NSSI...

THANK YOU! Its working again!
(Wiszę ci piwo.)

I have another question to you: do you have jumper manual to this card?
I no matter what i set i doesn’t work with my monochrome TTL monitor.

Not quite, but these may be helpful:

I tried those. No sync on TTL monitor.

Can't get it to work with my "Hercules" (I believe it's actually dual-sync, 15 and 18 kHz) monitor, either.

Normal VGA operation is:
all DIP switches ON
JP2 2-3

First, I toggled DIP switches 1 and 2.
Second, I toggled JP2 to 1-2.

In both cases, the same result: right after power-on/reset I can see the BIOS screen, but it's distorted (wrong frequencies?), and a moment later it goes all black.

Many thanks for checking it on your card.
Now i know its not just my card, i got similar symptoms to yours.

BTW: do you, by any chance, have the software for that card - or for any 8800-series card?

I'm especially interested in the SVM.EXE utility - described in that PDF manual.
It's easily found for 8900 and 9000 chips, but can't find any version compatible with 8800...

Sorry, i got no software nor drivers.
I wish had it too especially win 3.0 driver.

Hi everyone!

I had uploaded mine for a Brazilian clone version of the TVGA 8800CS here:

https://datassette.org/softwares/br-brasil-fi … cgv-tvga-8800cs

This version, signed by MICROTEC has a different character set, with a sans-serif font. I personally like it a lot. It is dated as of 02/06/89, v 1.0, model CGV - V.

On the other hand, I'm looking for an updated version for the BIOS of this board (higher than the 1.2, btw). There is a VESA driver for it that "updates" it, but I'd like to have it on the eproms directly.

Any ideas?

Thanks!

RC

I've never seen an 8800 card with VBE in ROM.
Most likely there's no such a thing - those cards are from the 80s, when VBE wasn't a thing yet.
