mdacon

[Christian H. <ch...@ku...>]

Hi,

the mdacon module doesn't detect my Hercules as a second adapter

	mdacon: MDA card not detected.

but stays in memory - bug or feature?

My question: Does anybody else discovered this problem and/or a solution?
My first card is a ATI 3D Rage Pro AGP (rev 9).

Christian.

Do you use a version from ruby's cvs?
Please try commenting out the two tests at line 217, and see if it then 
detects your card:

        /* Edward: These two mess `tests' mess up my cursor on bootup */

        /* cursor low register */
        if (! test_mda_b(0x66, 0x0f)) {
                return 0;
        }

        /* cursor low register */
        if (! test_mda_b(0x99, 0x0f)) {
                return 0;
        }

Try Matan's suggestion.

rmmod mdacon.o

If it fails to detect your card nothing is allocated and MOD_INC_COUNT
isn't called. rmmod will work to remove it.

I haven't tried it as a module. Since you have a second card as vgacon do
you have a second keyboard. This way you can have two functional VTs. You
can use vgacon as your debugging console while testing mdacon.
