Does QNX 4.X use video INT 10 for displaying CRT ?

No.

QNX 4.x runs in protected mode, so it can’t make BIOS calls.

What are you trying to do?

Hi Michael,

We use INT 10 to get into the graphics mode. After that
point INT 10 is no longer used.

Thank you for your reply.

If we use INT 10 in only text mode, is it possible ?

Hi !
I want to display text not on CRT but on LCD(128 X 64, 30 char X 4 line) in
our embedded system.
That’s reason why I asked viedo INT 10 a lot of times.

Thanks in advance

Hi,

Suggestion is get doc’s on video hardware(chips) and hit the registers directly.

Hi Michael,

Unfortunatly not, as QNX runs in protected mode, and doesn’t allow you to make
BIOS calls. I would follow Charles suggestion and see if you can find doc’s on
the chipset and try to poke the registers manually.

Also check to see if the “int10” utility would be of use to you. It “Provides
some INT 10 BIOS functions”. You would use it also if you are using the
Watcom Graphics Libs.

Erick.
