Hi punkgeek,
Sorry to ask a silly question but you do have scsi-4.8.17-tinycore64.tcz in your /mnt/sda1/tce/onboot.lst file?
If not, test by loading scsi:
sudo -u tc tce-load -i scsi-4.8.17-tinycore64.tcz
if that's solved your problem,
echo "scsi-4.8.17-tinycore64.tcz" >> /mnt/sda1/tce/onboot.lst
to load scsi drivers at boot.
for lsscsi,
sudo -u tc tce-load -wi lsscsi.tcz
That should put you in scsi heaven.
Regards
Philippe
