Hello,
I've got some problems to enable graphics with Dosemu. I think it's
because of the graphics card, ATI Xpert@Work 8MB AGP.
In console when I try to run Dosemu and "$_graphics = (1)", it all just
goes
black. I guess Dosemu doesn't run in the bg since blindly typing
"exitemu"
doesn't do what's supposed to happen. Luckily you still can switch to
another
console with ctrl-alt-F# combo and then kill Dosemu.
In X it'll start and all but when you try to run a DOS app/game that
tries to
switch to a graphics mode, Dosemu will crash without printing any error
messages into the xterm from which it was launched. When running
vgaon.com,
it'll say "ERROR: CAN'T DO VIDEO INIT, BIOS NOT MAPPED!".
Okay, here's my config (it's a patch againt the default Dosemu.conf
distributed with Dosemu 1.0.0):

The system is a P2/448MHz/Asus P2B mb/128MB SDRAM/Debian 2.3 (unstable),
ATI Xpert@Work 8MB AGP, XFree86 3.3.6, Dosemu 1.0.0. I've tried it with
kernels 2.2.14 and 2.3.99pre3.
The problem is probably $_vbios_* settings. I know for sure that the
address
of the Video BIOS is 0xc000. I've crawled through Dejanews and Dosemu
mailing
list archives before posting this message and somewhere I found a
message that
had instructions how to solve the VBIOS address with msd.exe of MS-DOS
6.22.
I'm not sure about the size of the VBIOS, though so I used the default
value.
Or then it's an AGP issue, or what do you think? Has anyone manage to
make
the graphic modes work under Dosemu using a system with any AGP board?
BTW. About the same config works just fine in both console and X with my
old box which has an S3 Trio64 graphics card. I've played many old
VGA games with that machine under Dosemu. I just wish I could do the
same
with the newer system.
TIA and regards,
