I have changed the Alpha port to use the new MI IDE drivers. This means
that ATAPI CD-ROMs and disk (e.g. ATAPI Zip drives) should work! You'll
need to make a few config changes. Basically:
% vi CONFIG_FILE
...and re-run config(8). (Make sure you have a new config binary installed,
per my post on current-users the other day!)
I have made the floppy driver sort-of work on my AlphaStation 500:

...unfortunately, DMA doesn't seem to work properly. In an effort to
find out if it's specific to the CIA chipset (i.e. a bug in the SGMAP
code I wrote for that chipset) or something else, I'd like for someone
with a Multia or AXPpci33 to test the driver. The reason I'm picking
that system is because I _know_ ISA DMA works on that platform, since
Curt Sampson tested my SGMAP code with an Adaptec 1542 in his AXPpci33.
If you can do this for me, please let me know, and I'll make a GENERIC
kernel available to you for testing.
