This README file of ISA311.EXE accompanies ISADISK.DSK for NetWare v3.11.

*  TBP302.DOC is a Techical Bulletin concerning the ISADISK driver.
*  FYI11081.DOC is an FYI giving tips for troubleshooting drive
deactivation.

Problems/Purpose Addressed:

ISADISK.DSK for NetWare v3.11, is meant to replace the former ISADISK
driver that ships with NetWare v3.11.  This file incorporates new default
loading parameters along with improved error handling capabilities.

Subsequent to some rare error conditions, the previous 3.11 ISADISK driver
would exit to the debugger.  That error path has been removed from this
driver.

With older ST506/412 and ESDI drives timing issues have been encountered. 
Symptoms include drive deactivation and/or a large number of redirected
blocks depending on which of the older ISADISK drivers is implemented.  If
the above symptoms are experienced and this driver does not remedy the
problem it is likely that there is another problem in the disk channel (see
FYI11081.DOC for drive deactivation troubleshooting tips).
	
This driver no longer requires the '/b' parameter to avoid the NetWare
Ready Sector or CCM Sector search.  The default (no parameter) is to bypass
NR or CCM.  In order to specify search for NR or CCM sectors on drives, one
must use either '/n' or '/N' parameter when loading the driver.  It is
important to note, however, that unless the drive is known to be a NR or
CCM sector drive, one should avoid the use of the '/n' parameter.

This driver may not require the '/l' parameter in many cases where the
previous ISADISK driver did.  The parameter is only to be used when a
controller or paddleboard is configured at I/O=170h.  Even in that case it
may not be necessary to use the parameter.

For an explanation of the /b and /l parameters refer to readme.311 located
on the SYSTEM-1 disk shipping with NetWare v3.11.

To install this version of ISADISK:

1)    Copy ISADISK.DSK to the same directory as the other NLM files on your
system (SYS:SYSTEM is suggested).

2)    LOAD ISADISK.DSK as you normally would.
