Hi: I've been doing some drive changes on my ST latelly and been needing a backup system. I've tried turtle but I haven't loads of floppies that I can use for this nor the time to sit in front of my computer all day switching diskettes. What I do have is a couple of UNIX systems (one system V and one BSD 4.2) with lots of disk space and 5 1/4 cartridge tape drives. I then started to consider using the UNIX system but had to get the information to it some how. I thought of using xmodem but it also required some intervention. I've been writing disk driver code for a while (my MAXTOR 380 meg ESDI drive) and all of a sudden it flashed on me to just convert the actual I/O routines in the driver so that instead of going to the DMA port, it went via the serial port. I over came the non re-entrant BIOS problem and wrote a handler that runs on the UNIX system. I can create a disk file on the unix system from 128K to 16meg, start the TSR driver on the ST and Wella... I've got a drive 'P' on my st that I can just drag files or disk ICONS to and start the copy and go away for a while. If used with a disk caching program this drive can be quite fast. Well I've been reading this forum for quite a while and have downloaded a lot of great stuff. If anybody is interrested in my code I will post it PD on this net or (try) to mail it to whom-ever asks. Currently I am working on another UNIX side utility to copy to and from files from UNIX and the ST disk file. ---- .===========================================================. | ### ####### ### | N O R T H | /==============\ | | ### ### ### | A M E R I C A |< An STC Company >| | ### ####### ####### | (was CCI) | \==============/ | |-----------------------------------------------------------| | UUCP: ...ccicpg!dl2!paulm | Paul L.

But, your ideas sound good anyway. I have a thought, would it be possible to interface an ST to an IBM PC with a tape backup?? More folks out there might have access to such a creature. There are a lot of Bourneoulli (sp?) boxes out for IBM PCs, and other forms of tape backup. But, except for the ICD FAST TAPE, which is $900 plus tapes, and the SysQuest 44 meg removable drive, which is $800 plus $110 per cart, there is very little way of backing up a large hard drive. So, your ideas are most welcome. . . . . . . . . . . . . Richard Covert

But, your ideas sound good >anyway. I have a thought, would it be possible to interface an ST to an IBM PC >with a tape backup?? More folks out there might have access to such a creature. Did you look at the code? I wonder how well it would run over a telebit to a unix host (in xmodem mode instead of uucp mode). I had given some thought of doing something like this for a PC. The machine in my living room has 2 337MB drives, but the one in the kitchen does not have a drive for DOS. I am not familiar enough with the ST to even think about doing what Paul has done. The C portion may be able to be ported to a PC allowing the PC to serve the ST. I tried Paul's program connected to a 286 running Xenix and all i get are "Chksum reading block 0" and then "Timeout" errors. Has anyone been able to get this working on a ST talking to a 286 or 386? I tried running it at 4800 baud with the exact same results, the only thing i can think of is that the data that the ST requires is byte swapped. I have been giving some thought to using Paul's Unix partion of the code to serve to a DOS machine allowing the same server software to work with both the ST and PC. Anyone interested in swapping ideas? Please respond via mail if you are, or know what the problem is with running the C portion on a 286. Is there a simple Backup program that works on a 520ST? The ST's hard drive was dropped and i did not have a backup, hence my desire to get pmfs working. -- Mark Seiffert, Metairie, LA. uucp: rex!mgse!marks bitnet: marks%mgse@REX.CS.TULANE.EDU internet: marks%mgse@rex.cs.tulane.edu
