Please bear with me -- this may seem like stupid questions but I need answers... First, on an ESIX (386 Unix) system, how would I build a minimal boot disk to recover my system from a CPIO tape from a crash? The tape is a Wangtek 5150 SCSI device. I have the drivers currently installed (obviously!). Second, how difficult is it to embed a foreign device driver in a disk build set? Reason: We are looking at implementing Unix as our system platform, but we need to use a SCSI device driver from a different vendor. The Unix we wish to use doesn't know about this driver, so their build disks don't have it. The SCSI vendor has a driver which will work on a different 386 System V-derived system (if you want the gory details, the other 386 system is SCO Unix, the SCSI vendor I cannot name). What I would like to do is build a system generation diskette set with this driver slapped in. Are these possible? How difficult? Should I seek therapy? -- .-------------------------------------------------------------------------. / [- O] Rick Stevens (All opinions are mine.

I just got thru building a disaster disk for my system, after reading some articles from others on the net who have done the same 8^). The place for you to start is make a copy of your ESIX boot/install diskette. Put the diskette in the drive and mount it like so: mount /dev/dsk/f0 /mnt. You'll get a message warning you about install mounted on /mnt, this is because the disk file system name doesn't match the name of the dir you're mounting it on (see labelit(1M) ). Now you can just cd into /mnt and start exploring. The biggest problem I ran across was disk space, my floppies only hold 1.2MB and I was hard pressed to fit everything I wanted on the disk. You may want to strip all the utilities on the disk and replace the unix on the disk with a minimally configured kernel you build via kconfig. It can have *just* those drivers required, mine has the Wangtek driver in it so I can boot from floppy, much around with the drive with the disk* utilities, do my mkfs's and restore from tape. Remember to mknod the tape devices on the disaster floppy after copying your minimally configured unix to it. -- Arthur W.
