Bring up a liveCD or moral equivalent and run SLIP, then do any of many
networked-backup variants?
Hmm, was SLIP an option for DOS TCP/IP stacks? I'd not considered that
because I've only ever used TCP/IP in a DOS environment against Ethernet
hardware, but if I could get SLIP up and map a DOS drive letter to a remote
mount point, that would probably do the trick...
SLIP at 115200 is only about 1% of a 10Mb
Ethernet, but that may be enough to be useful, especially if you
compress.
I'm not sure if something with e.g. an 8088 CPU can even come close to that
- maybe 9600, tops.
I'd be expecting several hours of transfer for a typical 20MB ST506-type
drive, assuming it was doing raw sectors rather than just "in use" data -
but I think it's the only option in some cases where Ethernet or
sneakernetting data via floppy isn't viable.
Alternatively, maybe move the DOS disk to the other machine and copy it
there with dd or moral equivalent?
For anything modern with IDE or SCSI, sure, but not so easy for
ST506/ST412/ESDI :(
