Quoting a message from Wan-Yik Lee:

Hmmmm.....  How about a faster disk I/O channel?  NetWare v4.1 also
is much more efficient during the boot process, so perhaps an upgrade
is in order.

Only one directory table AFAIK.  FATs are indeed verified.

Why would you want to do something as dumb as not verifying data
integrity?????

Yes, no.  What may be the largest factor in the apparent slowness you
describe is the rest of the volume mounting process.  First, NetWare
builds a copy of the entire FAT of every volume in RAM.  Second, it
builds an index (called a Hash Table) of the Directory Table, and
caches the index in RAM.  Believe me, you don't want NetWare to *not*
do those things!!!  Not with as much as 50 gigs worth of data stored
on there you don't!

These functions are core to the NetWare operating system, and there's
no way to turn them off.
