In addition to the TCP/IP-specific tools mentioned in this chapter, the MBA Utility
Disk includes other tools that help simplify the installation and use of MBA. These
tools are outlined in this section.
FREEMEM: Free RAM Disk Memory
FREEMEM releases all the memory used to transfer the boot image file from the
server after the PC has booted. It also changes drive A: back to the local floppy
drive (drive A: is used as a RAM disk while the PC is booting from the image file).

Before you can use FREEMEM you must change your DOS
COMSPEC variable to a DOS directory on the network,
otherwise you will get an error when DOS tries to reload
COMMAND.COM after FREEMEM terminates.
FREEMEM can not be included in the image file; it must be
executed from a network drive (or local hard drive).
After using FREEMEM you should have about 2 KB less memory
available than you have when you boot from the diskette used
to create the image file.
BPPATCH: Supporting Replaceable
Parameters
The BPPATCH program is used to replace parameters from the BOOTP/DHCP reply
packet into text files. This allows one common image file to be used by several
PCs, with the parameters unique to each PC (like the IP address) being specified
in the BOOTPTAB file on the server and replaced in the image file when the PC
boots.
