MKDRIVEA.COM: Using VDISK.SYS and MAPGEN.COM in diskless workstations
Product(s) Afffected:
All diskless workstations with 3Com MBA wishing to
use VDISK.SYS (or equivalent), or MAPGEN.COM
Problem:
When a virtual disk is created using VDISK.SYS, the message
"Invalid drive specification"
is displayed when attempting to access the virtual disk after
the NetWare shell is loaded.
When using MAPGEN to map a DOS image file to a local drive
(drive A: for example), the same error message is displayed.
Solution:
The problem occurs because a low-level BIOS variable informs
the NetWare shell that there are no local drives. Using
the CONFIG.SYS "LASTDRIVE" statement will not solve the
problem. After the NetWare shell is run, SYS:LOGIN will be
mapped to drive A:.
The solution to this problem is to run MKDRIVEA prior to
running the NetWare shell. This program is run by AUTOEXEC.BAT
(or PRESHELL.BAT if you are using it). MKDRIVEA.COM must be added
your DOSGEN image.
MKDRIVEA will operate in workstations with close-compatible BIOSs,
and will not affect the operation of workstations which actually
do contain physical drives.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
