Disaster Recovery Disk and Driver Installation

[rick at tmiuv0.uucp]

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?
