Boot Using MBA
The PC can now be booted using MBA. Perform the following steps as needed:
22.
For multiple PCs to boot using this file, it must be flagged as shareable. When
Boot Image Editor creates an image file it automatically flags the file as
shareable. If you need to set it manually (for example, if you created the
image with DOSGEN), use the NetWare FLAG command:
flag net$dos.sys sh (for netware 4.x and 5.x)
or
flag net$dos.sys s (for netware 3.x)

If your network has more than one file server, copy the boot image file and
AUTOEXEC.BAT to each server's SYS:LOGIN directory. If you use the optional
MSD NLM, you do not need to worry about copying these files across all file
servers. See “
Multiple Servers: How the MSD NLM Can Help
” in this chapter.
You have now created a single boot image file that any PC with MBA installed can
load and boot from the network. If your MBA-equipped PCs have different booting
requirements, there are two ways to meet these requirements:
You may use the CHKID and ROMTYPE utilities (provided with MBA) which
allow you to load drivers conditionally based on node address or NIC type.
You may have to create additional boot image files if different operating
systems are used. See “
Supporting Different PCs with One Boot Image
”,
and “
Creating Additional Boot Image Files
.”
Creating Additional Boot Image Files
It is likely that more than one boot image file will be required to suit the differing
needs of the PCs on your network, especially if different operating system versions
need to be supported. Supporting multiple boot images requires an understanding
of three important issues:
Creating/editing the BOOTCONF.SYS boot index file
Avoiding AUTOEXEC.BAT conflicts in SYS:LOGIN
Using Boot Image Editor to create different boot images
Creating and Editing the BOOTCONF.SYS
Boot Index File
The default boot image file is NET$DOS.SYS. When you need to support more
than one boot image file, you must name these files in a special boot index file
called BOOTCONF.SYS.
The BOOTCONF.SYS file is an index of all the boot image file names and the
network address and node address of each PC that must access those files. This
file must be in the SYS:LOGIN directory.
MBA (or the MSD NLM, if loaded) scans the contents of BOOTCONF.SYS during PC
boot, and if no entry is found which matches the PC's network and node address,
the default boot image file is used.
The BOOTCONF.SYS file may be created and edited in the following ways:
