How do I disable FFS?

[Tim Addington]

I recently upgraded my system to a 650 Meg SCSI drive.  My question is
is there anyway to speed up the mounting and dismounting of the various
filesystems.  It is taking about 10 minutes now to bring up and shut down
the system.  Is this due to the Fast File System or the High Performance
Disk Driver or what.  I would like to disable this while I am setting up the
system.

The system is configured as follows:

	ISC 2.2
	Micropolis 680 SCSI Drive
	Adaptec 1542A Controller
	8 Meg RAM
	386/25
