I haven't looked at the List for a while, so I only saw your message
yesterday. In the mean time, I've re-learned to work with bootable
memory sticks. I've had no luck yet with ReWritable CDs which I need for
all boxes but one. Perhaps a blanking problem?
Here is the summary of my trials in Fixit mode for my Sony DSC-P10 which
is also (at last) the answer to Jeremy's message:
booting OK, but
"No USB devices found!"
CAM status: SCSI Status Error
SCSI sense: UNIT ATTENTION asc: 28,0 (Not ready to ready
change, medium may have changed)
da0: 1915MB (3922944 512 byte sectors: 255H 63S/T 244C)
GEOM: da0: media size does not match label.
Is it not a case for send-pr(1) ?
