Title: CacheCDFS multiple LUN Settings (CD Changer)
Post by: Hybrid on June 29, 2006, 04:22:04 PM

Hello there!!

Im busy putting the final touches to an A4000D to re-launch an old BBS. One stumbling block is getting my Nakamichi 7 Disk CD Changer to work with CacheCDFS.

The DosDriver entry that gets the first CD in the changer going is below (ID 4 LUN 0). This works fine but of course is only for the first disk in the changer.

What changes to this mounlist do I need to make to get CD01: etc to be recognised (ie ID 4 LUN 1,2,3,4,5 and 6)?

Many thanks

Paul (Hybrid/Digital Candy)

Unit = abc

a = board
b = LUN
c = ID

so
unit 4 = LUN 0 at ID 4
unit 14 = LUN 1 at ID 4
unit 24 = LUN 2 at ID 4
etc.


For UW-SCSI with numbers larger than 7 it is
