Use the following
*BUILD !BOOT
This will prompt you with:-
0001
type what you want to do:-
it will prompt you with 0002 etc
0001 @MLOAD "ROM1.ROM" <return>
0002 *MLOAD "ROM2.ROM" <return>
0003 CHAIN "PROGRAM"
when you have finished typing commands, end with Escape.
You'll have a !BOOT file on the disc, you can use *TYPE !BOOT to check
contents, and *EXEC !BOOT to Execute the file.
If you want to Shift Break and boot the disc use
*OPT 4 3 to change the disc to EXECUTE (EXEC).
I forget what the exact Master commands are to load ROMS into Sideways RAM,
but I'm sure someone knowledgably person will answer that one, from memory
I'm not too sure if these ROMS will be available immediately until a
Control-BREAK is pressed, of the appropriate command is sent to do this.
Once again I'm sure it will be answered quickly.

Dear All
How does one go about making a bootable disc on the BBC. What I want to do
is to load two ROMs into sideways ram on a master then to chain the rest of
the programs. I notice that there is a !BOOT file on most discs but I have
no idea how one opens this or edits it. Any help would be appreciated.
Please bear in mind that I am a relative novice on the BBC.
Thanks
Alastair
