IGURE IN RADITIONAL NVIRONMENTS
How MBA Works in a TCP/IP Environment
To boot the PC, the MBA ROM first sends a broadcast to all of the servers on the network to
see if one of them is running a BOOTP or DHCP service and has the required information for
the PC (PC's IP address and boot image file name). The response from the server provides
the PC with its IP address, the name of the boot image file and the IP address of the server
that has the image file.
The PC then sends a TFTP request to the server to transfer a copy of the boot image file. This
image file is stored in the PC's memory as a RAM disk. When the entire file is received, MBA
passes control over to the downloaded file. The PC boots just as it would from a diskette.
After the PC has fully booted and connected to the network, the FREEMEM utility can be used
to remove the boot RAM disk, and restore drive A:
to the local floppy drive, if it exists.
