Operating System Dump?

[+Larry]

Is there an Atari program that will properly dump the 16K XL/XE-type OS?

I seem to remember that it is not a straight-forward proposition, unless of course, the OS rom/eprom is pulled and read in a burner.

I'm looking for a program that reads it in situ.

Try this simple BASIC program which I cut and pasted from the old Rainbow emulator's documentation...

 

5 REM CREATE 16K XL OS ROM FILE - 16384 BYTES

 

10 OPEN#1,8,0,"D:ROM16K"

 

20 FOR K=49152 TO 53247 : PUT#1,PEEK(K) : NEXT K

 

30 POKE 54017,PEEK(54017)-128

 

40 FOR K=20480 TO 22527 : PUT#1,PEEK(K) : NEXT K

 

50 FOR K=55296 TO 65535 : PUT#1,PEEK(K) : NEXT K

 

60 CLOSE #1

Since it's a 16K ROM but maps to different regions, you just need to do the following:

 

Dump the $C000-$CFFF 4K portion. (4K)

 

Enable the Self-Test ROM, then follow with the $5000-$57FF portion (remaps from $D000) (2K)

 

Follow with the $D800-$FFFF portion. (10K)

Hi

 

This is my OS dumper program I posted some time ago on comp.sys.atari.8bit:

 

10 OPEN #1,8,0,"D1:OS.BIN":PRINT "DUMPING OS..."

20 PRINT "$C000-$CFFF":FOR I=49152 TO 53247:PUT #1,PEEK(I):NEXT I

30 PRINT "$5000-$57FF":POKE 54017,125:FOR I=20480 TO 22527:PUT

#1,PEEK(I):NEXT I

40 PRINT "$D800-$FFFF":POKE 54017,253:FOR I=55296 TO 65535:PUT

#1,PEEK(I):NEXT I

50 CLOSE #1:PRINT "OS DUMPED!"

 

It works 'saweet'.

Thanks, everyone! I thought that I remembered seeing one somewhere, but forgot it was in CSA8.
