Hi,
I don't know if anyone is interested in this, but I've recently purchased
a 7-drive tower full of 4-disk 8x Nakamichi CD-ROM changers. These units
each take up the space of a standard 5 1/4" half slot, but are 4-disk
changers so you can get effectively 28 disks into one normal tower unit.
Anyhow, I had to add the following lines to scsiconf.c - I hope this diff
is useable - I'm not too experienced at such things. It is relative to
3.0-SNAP of 18/01 but it should be easy enough to adapt for other releases
too I think.
This server won't go online for a couple of weeks so if anyone wants me to
test out CD-ROM changer code I'll be happy to oblige. The drives are
connected to an Adaptec 2940 SCSI II card. The machine is an Opus Pentium
P75, 24Mb RAM, with an SMC 8216T ethernet card, 1.2 Gb IDE hard disk on
one channel and an 8x IDE MATSHITA CD-ROM drive as primary on the other
IDE channel. The hard disk is partitioned into to 600Mb chunks, the idea
being I can run an experimental 3.0 system on one chunk and a more stable
2.2 system on the other - I'm waiting for 2.2R for the second chunk.
Access to the CDs will be via NFS and Samba as we have a mixture of older
PCs running PC-NFS and newer machines running NT 4.0. I already have two
networked CD-ROM servers running 2.1R with this kind of access so I know
what I'm doing (famous last words...).
