[9fans] fileserver to PC port???

[Bengt]

greetings,

the plan9 cd-rom has a fileserver for pc (9fs) that only does scsi disks.
the toronto faq mentiones that there is a user contributed fileserver for pc.
conceivably this could mean a 9fs for ide disks. or somehting else.

i would be interested in a 9fs for ide disks. all my scsi disks are internal
(and in use), but i have a 1 GB ide disk laying around.


Best Wishes, Bengt

I have such a beast; it works but doesn't take advantage of the more
'esoteric' DMA and PIO options.  If the original poster is still
interested he can email me directly and I can send a diff.  Note
that it won't fileserve out of partitions, but uses an entire disk just
like the scsi implementation.  I've used it on 2 disks stacked together
as a single striped filesystem, and should work with 4 disks.

The PC ide interface is unnecessarily complicated with much legacy cruft.
Adding more PIO and DMA flexibility would not be difficult but
exceedingly tedious (see freebsd WD driver: yuk!)  .  IMO scsi is a
better win for FS's even for small #s of disk units, if only from an
ease of implementation standpoint.

years ago for someone else i did a quick version of 9pcfs
that supported IDE discs.  i can't find the changes,
which implemented the file server's scsi
interface to a modified devata.c.
