[comp.sys.ibm.pc.hardware] video problems

Robert_Bell@mindlink.UUCP (Robert Bell) (04/01/91)

I am wondering if anyone has had a similar problem to what I am experiancing at
the moment.When ever I use games that use 256 colours such as wolfpack or f19
some of the main screens deteriorate,by this I mean some of the pixels change
colour and I get long lines down my screen(like rain).Also when i use Quick C
with the /h option ke rain)
inorder to use the editor with 50 lines,all the text output from my programs is
jumbled up or missing.I have a feeling that the problem is with my video board.
By the way my equipment is as follows:-
 12mhz 80286 clone
 wd 40 meg ide drive
 trident 8800 vga board with 512k ram
 datatrain dc-507 vga moniter
I also have the following boards installed :-
 1,ADLIB
 2,LOGITECH SCANMAN BOARD
 3,2400b INTERNAL MODEM ON COM 1
 4,I/O BOARD
 5,IDE CONTROLLER

Hi,

	I too had problems with my Trident VGA card 1MB. It conflicted with 
my ST01 SCSI card. I solved the problem by turning the fast address decode
switch off. I think we both have the same card. You switch dip switch 5 to on.
If the problem sill persist try changing the auto channel dectect to 
standard. Can't remember which jumper this it, you should be able to 
find it in the manual that comes with it. 

	I think that your VGA card most likely conflicts with your scanner,
since I have a 80Mb Maxtor (I think IDE) drive. Adlib shouldn't cause much
problems. If the above doesn't help try writting down all the access range
(memory) of each card. If there is conflict than try to change one of them.
If the interrupt lines conflict try to change it too.

	Well, I hope that helps, you really need to check all the manuals
when installing. Especially if you install new cards after the system comes
to you. I have a friend, he blew his CMOS and several chips when he plug
in his SCSI card. The best part of it, it didn't happen immediately, but
rather 2 weeks after he installed it. Strange huh?

	Good Luck!

Michael
