Real Time Devices (RTD) CM112 Utility Card with CT65554 grap

QNX Newsgroups (Archives) qdn.public.qnxrtp.installation

Anyone,


Has anyone gotten higher than 640x480/16 color resolution with a Real
Time Devices CM112 Utility card with the Chips and Technology CT65554
video controller? The default driver in QNX6.1 can’t deal with the
fact this contorller uses an ISA bus rather than PCI. I can get the
card up and running under win98 using the most generic Microsloth
driver. I’m told its an issue of address space for video bios. ISA
can’t address enough space so the video bios needs to get chunked up
into a nonlinear (continious) memory segment.

The default graphics driver loading command is
io-graphics -g640x480x8 -dldevg-vga.so -P/usr/photon/palette/vga4.pal

I have tried modifying this to forc the Chips driver to load
io-graphics -g640x480x8 -dldevg-chips_hiqv.so
-P/usr/photon/palette/vga4.pal

I just get the error
mode_init: Bad file Descriptor

I tried playing around with crttrap without any success: Where do I
go from here? This card is listed as supported on QNX 4.25 I tried to
find that & download it with out any success finding an iso for it
even.

Thanks in advance

Hi,

Could you install Patch A on your system, and then try adding
the line:

echo(devgt-iographics -dldevg-chips_hiqv.so, $(fname))

to the end of the /etc/system/enum/devices/graphics
where there is a check for non-pci devices.

You should then be able to reboot and run crttrap trap
to get the C&T driver.

Regards,

Joe

Joe,

It appears I may have confused you a bit or I am just completely
confused (the latter has a high probability). It seems to me that
patch a is applicable if you had a windows os and then installed qnx
on top. I have 2 hard disks with only one in my system at a given
time. One win98 & 1 QNX. After talking with Real Time Devices the
trick is to prevent the chips driver from using linear mode. This is
why the generic win98 driver works on the windows drive. So does the
Patch A and below command line still apply to my situation with a
dedicated QNX installation?

Thanks,

Erick

Hi Erick,

According to the developer if you device doesn’t work in linear
mode then you won’t be able to use the devg-chips_hiqv.so driver.
The suggestion is to try using the devg-svga.so driver instead
as it does not require a linear buffer.

Regards,

Erick.

Joe,

I tried your suggestion with a stand alone install of 6.1
echo(devgt-iographics -dldevg-chips_hiqv.so, $(fname)) at the end of
/etc/system/enum/devices/graphics

I reboot & photon comes up and finds a new video card and but fails to
vga mode.

I exit photon an login to prompt and run crttrap trap

& Get
"
/usr/photon/bin/devgt -iographics -dldevg-chips_hiqv.so
mode switcher init: Bad File descriptor
crttrap: did not find any video modes: resorting to VGA driver

"
do you think the driver file might be bad? i did try to open it with
the editor before but i didn’t think I saved it. If you think so how
do I get it back - without reinstall?

Hi,

Patch A is for a dedicated QNX Install, you can install it from the WWW
repository via the package installer → your suspicion below about the driver
being “bad” is correct. You can also get a new driver from developers.qnx.com
under Fixes. (chips_fix.tar.gz)

Joe

Joe,

I tried the devg-svga.so
driver in the same fasion
echo(devgt-iographics -dldevg-svga.so, $(fname)) at the end of
/etc/system/enum/devices/graphics

& Get
"
/usr/photon/bin/devgt -iographics -dldevg-svga.so
crttrap: did not find any video modes: resorting to VGA driver

"

Any more suggestions?
