I have encountered a couple of problems with my VGA card...

I received a video game for Christmas called Lemmings. I tried it on
my system but the mouse cursor was messed up. It looked as if the
byte order of the cursor was reversed when it restored the patch of
screen it was passing over. Anyways, it royally messed up the screen
and made things unreadable. Also, The cursor seemed to jump (teleport?)
to other parts of the screen without provocation, usually to a point
directly above or below the current point. I've had this kind of problem
with other video games too. I've seen Lemmings working well on another
machine.

Also...

My VGA adapter screwed up on me. I was playing around with the configuration
program in an attempt to get the mouse cursor to work properly. The card has
two connectors on the back, one for a vga monitor and one for an ega
monitor. My monitor was on the vga port. In the vga setup program menu
(VSETUP) there is an entry to switch the card to the ega connector.
In hopes of fixing this mouse cursor problem I switched to ega. Now
when I reboot the system displays two version lines on the vga screen
reinitializes all the disks and then hangs. If I plug an ega monitor
into the ega connector and remove the vga monitor the system reboots
fine but now I don't have the resolution of the vga screen. If the vga
monitor is connected to the vga port (even powered off!) the system will hang.
If I go back into the setup program and try to set the card back to vga
it won't let me select the vga option in the menu. It skips over it.

My system is an AMI 386 running at 33 MHz and with 4 Meg of memory.
The board is an ATI VGA Wonder card. I managed to extract the following
info from the ATI BIOS information block:

Signature code:			31 = VGA WONDER
Chip version:			2 = ATI 18800-1
BIOS version			1.0

Uses paged ROMS			no
8514/A hardware on board	no
32K color DAC on board		no

This video adapter is a VGA WONDER V5
Amount of RAM on video board 512K

What I would like to know is:

Is the cursor problem a bug in my card? Is there a fix?

and (more importantly)

What did I do to my card? Can I fix it? Am I stuck with an EGA card now?

Thanks in advance.
