If the manufacturer doesn't provide me with the specific values for NANO_SECTS, NANO_HEADS and NANO_MEDIASIZE, I assume that I would be able to use the output of fdisk to calculate it for me: fmybox# fdisk /dev/ad0 ******* Working on device /dev/ad0 ******* parameters extracted from in-core disklabel are: cylinders=993 heads=16 sectors/track=63 (1008 blks/cyl) parameters to be used for BIOS calculations are: cylinders=993 heads=16 sectors/track=63 (1008 blks/cyl) So in this case, NANO_SECTS=63, NANO_HEADS=16 and NANO_MEDIASIZE=(993 * 16 * 63)=1000944? I added the following to Flashdevices.sub: dom512m) # Source: sbruno@miralink.com NANO_MEDIASIZE=`expr 512483328 / 512` NANO_HEADS=16 NANO_SECTS=63 ;; If I do this for my new Transcend module, the system won't boot properly and freezes on the BTX boot loader startup. What am I doing wrong here? Sean
