Chapter 5 SCSI Drive Installation 59
Remember, no spaces are allowed in specifying a command line
option for SCSIDISK.SYS.
Note:
It is illegal to exclude a device for which an NCR boot
ROM is providing an INT 13 interface. SCSIDISK.SYS
will print an error message and will control those devices.
Also, there is a limit of 24 ‘path:id:lun’ combinations
allowed.
Using the /SSIZE= Option
SCSIDISK.SYS will default to the largest sector size found during
boot. If no media is found in a removable media device,
SCSIDISK.SYS will assume a 512 byte sector size. This option
can overcome this default: To use this option, the line in
CONFIG.SYS that loads SCSIDISK.SYS should look like this:
DEVICE=C:<PATH>SCSIDISK.SYS /
SSIZE=512|1024|2048|4096
For example, if a removable media drive is used that has a sector
size of 2048 bytes, the command line should be:
DEVICE=C:<PATH>SCSIDISK.SYS /SSIZE=2048
Remember, no spaces are allowed in specifying a command line
option for SCSIDISK.SYS.
Note:
If SCSIDISK.SYS comes across a sector size larger than
the one specified in this option, or if it finds a sector
larger than the default, it will refuse to read/ write to that
media. It will report an invalid media error to DOS.
