Problems getting target mode to work with isp driver

[Matthew Jacob]

To a first approximation, it worked for me on a 24XX:

localhost.localdomain > lsscsi
[4:0:0:0]    disk    SEAGATE  ST314655SSUN146G 0791  /dev/sda
[4:0:1:0]    disk    ATA      ST3500630NS      G     /dev/sdb
[4:0:2:0]    disk    ATA      ST3500630NS      G     /dev/sdc
[4:0:3:0]    disk    ATA      Maxtor 7Y250M0   1EW0  /dev/sdd
[4:0:4:0]    disk    ATA      ST3500630NS      G     /dev/sde
[4:0:5:0]    disk    ATA      ST3500630NS      G     /dev/sdf
[4:0:6:0]    enclosu ESG-SHV. SCA HSBP M1..... 2.09  -
[6:0:0:0]    disk    FreeBSD  Emulated Disk    0.1   /dev/sdg


It's entirely 23XX is broken. I'll see if I can hook one up and let you 
know.
