That's the Trident chipset and BIOS that is installed on your machine.

Trident cards seem to be very popular in the Far East at the moment, we
get all our DataExpert machines supplied with either an 8 or 16 bit Trident
card and we have never had any problems with them.  The card should come
with a disk of drivers for popular software.

I have come across a couple of hassles with my favourite programs (VPIC
etc) not working properly with the Trident VBIOS, I think it is just a 
matter of time before there are enough in the US market to make direct
support by software authors worthwhile.

I have never had any hardware problems or incompatibilities with the card,
however a couple of months back someone in Australia mentioned having a
hard time getting it to sync properly in 1024x768x16 mode: the cure was
to replace the 40.000 MHz crystal on the card with a 37.500 MHz one.  I 
have never personally done that so can't say for sure if it works, or if
all TVGA cards will have the same fault.

Disclaimer: Computer Sciences NZ has nothing to do with DataExpert computers.
I own half of the company which has the New Zealand distributorship for DE.
