Hi,
There is a possibility that you can apply INT 16h, AX=0304h with
your BIOS (if you haven't tried it yet).
According to Ralf Brown's Interrupt, it turns off typematic repeat
on some machines.
In case it doesn't work for you, you'll probably need a small TSR
that would intercept IRQ1 (INT 09h) and reject all
key-press scan codes (with bit 7 clear) not immediately preceded
either by key-depress scan codes (with bit 8 set), or by
a Shift/Ctrl/Alt press code. (This is the way I can imagine it now.
Has anyone a better idea?)
There can also exist another solution specific to your BIOS,
impossible to find without disassembling its INT 09h routine,
but the hope is rather small.
Hope it helps.
Greetings,
Michal
