No, not as far as I know.. I'll try to build 2.6 on my Amiga with the GG
card soon and post the driver ont he list.
The 'driver' (if you can call it that) for the card pretty much does nothing
anymore, just flip some bits on the card to enable it's interrupt forwarding and
enabling or disabling the waitstates on the ISA BUS.
Because most i386/ISA drivers these days can handle shared/chained interrupt
handlers like we always had on the m68k it's no longer needed to set up a
secondary IRQ handling for the ISA drivers. (like I had to do for 2.2)
After that it's just a matter of some macro's for the byte-swapping of
the ISA data and the address mangling for accessing the I/O and memory space.
Of course no DMA support and such, so no need to mess with that..
Bye, Arno.
