Hello Jim!
You are almost right. I look at source code and found, that
minor number 0 for rewinding,
minor number 1 for non-rewinding. For the same device, of course.
For second device, I thing, it will be 2&3.
Now, I can describe all the way.
1) insmod tape390 tape=<address>
Driver uses major number 254 (in my case)
2) cd /dev; mknod ntibm1 c 254 1
3) mt -f /dev/ntibm1 rewind
4) dd if=image of=/dev/ntibm1 bs=1024 # write kernel image
mt -f /dev/ntibm1 eof 1 #
write EndOfFile mark
dd if=parmfile of=/dev/ntibm1 bs=1024 # write parmfile
mt -f /dev/ntibm1 eof 1 #
write EndOfFile mark
dd if=initrd of=/dev/ntibm1 bs=1024 # write ramdisk
image
mt -f /dev/ntibm1 eof 2 #
write EndOfFile mark twice - for sure :)
5) mt -f /dev/ntibm1 rewind
You have the correct tape. Easy :)
