[comp.unix.sysv386] Any success using a Perstor ARLL controller with Microport SysV/386?

di@hstbme.mit.edu (David Israel) (09/06/90)

A friend of mine recently bought a Perstor ARLL controller that he
would like to use with Microport SysV/386 v3.0e.  However, he found that
he could not get through the install procedure (he has no trouble 
installing with an MFM controller), even though the hardware works
fine under DOS and Microport supports RLL controllers by allowing a
user-selectable number of sectors per track.  Has anybody
managed to install Microport System V/386 on a machine with this
controller?  If so, could you provide details?  Failing that, does
anybody know whether this controller is usable with any of the other
386 Sys V versions?  Thanks.

a few questions. What did he use to low-level the drive, how did the install
fail?

Some controllers forget about the existance of any other os other than
MS-DOS and mark the ENTIRE track bad when they find a bad sector. This
will add 26 entries (26 sectors/track) into /etc/partitions on the uport
install quickly blowing the 64 entry limit.
