Q: How do I back up an S900/S2000 floppy disk?
A: If you're using linux and have a recent version of fdutils installed, you can always use s2kdie.
The commands after running the script to back up an S900 floppy disk would be:
For an S2/3K it would be the same, but simply LOAD instead of LOAD -S900.
If you want to do it without the script, first you need to set some floppy drive parameters.
setfdprm /dev/fd0 sect=5 dd ssize=1024 cyl=80 (for S900/S950)
Then you can simply "cat /dev/fd0 > imagefile" or vice versa to restore the image "cat imagefile > /dev/fd0"
Q: Do you have the S900 operating system upgrade disk?
