It's a patchset to bring Micro Channel Architecture support
(bus used in some old IBM PS/2 machines) into -current.
It's based upon Scott Telford's and McGarry's MCA code.
Almost no devices is supported - the only provided drivers
(besides ISA lpt, com, vga and floppy) are IBM Tropic
Token-Ring adapter driver (wrote by McGarry) and AHA-1650
driver, both of them were not tested by me yet. Most
notably, ESDI driver is not present ATM.
It's available at
Boot floppy with older kernel is at
It's of course possible to replace the kernel at the
provided floppy image with newer - you'd need to compile
your own kernel for that though (kernel configuration file
is attached to the patchset).
See the README and dev/mca/TODO for drawbacks
and current limitations. Note that this is work
in progress and I'm not able to offer much support
ATM in case of problems (though I'll try if needed).
Any comments, criticism, success/failure stories
would be welcome.
