6.12. How can I modify the kernel to work with my graphic card?

mtk says:

Ok, from my memory, these files need to be changed:

grfvar.h add defines for your board analogue the others
device.h add manufacturer/product code
autoconfig.c add man/prod to switch statement, and set to BITMAP type
write grf_XX.c and ite_XX.c, look at the existing drivers in general, grf_ should deal with the framebuffer as such, and ite_ should care about the framebuffer in text-mode, ie. drawing characters, scrolling lines, etc.
add your board to the dispatch tables in grf.c and ite.c
add - if necessary - new grf1 entry to conf/AMIGA
add your new files to conf/files.amiga
reconfig the kernel, make, cross fingers, debug ;-)
