bootup. The simplest solution is to change your com-
puter’s parallel port hardware to LPT2 or LPT3, or
change your network redirection to a different port.
The MiniSCSI EPP Does Not Function
1 In the mode configuration switch /M
nm
at the end
of the line device=[path]ma358.sys in your
config.sys
, set the value of
n
to 1.
The /M
nm
switch must have both
n
and
m
values
specified. For example, enter /M70 (
n
or
m
must
be set to 0 if not being used). (See Device Driver
Options in the Software User Guide.)
Note: For non-Intel 386SL or 486SL based
computers, modify the value of
m
first. Set
the switch to /M08 to force EPP mode. Then
follow the tests in
a
through
c
. If you dis-
cover problems, modify the
n
value as
explained in steps 1 through 3.
After setting the switch, perform the tests below
to ensure the adapter is functioning properly:
a Perform a dir command on a hard disk drive
and/or a CD-ROM drive. Check if a problem
is evident, such as absurdly wrong numbers or
corrupted file names being reported.
b Try copying a large (greater than 100 KBytes, if
possible) file from the SCSI device to a non-
SCSI hard disk or floppy drive. Then use the
DOS comp command to compare the new
copy to the original file. Check if a problem is
evident, such as the file comparison failing.
c Copy a large file from your non-SCSI drive to
a SCSI rewritable device. Again, compare the
two files with the comp command. Check if a
problem is evident, such as the file compari-
son failing.
2 If your MiniSCSI EPP still does not function prop-
erly, repeat step 1 with other
n
values such as 2, 3,
4, 5, 6, and 7 until the adapter works. The idea is
to optimize performance by selecting the lowest
n
