bios2dump.c - Was designed to dump memory block to file.
|
||
|
|
Usage: as argument requires absolute address of memory dump and its lenght
|
||
|
|
(int hexadecimal form).
|
||
|
|
as output - will write file which will named: memADDR_LEN.dump
|
||
|
|
where: ADDR - given address of memory
|
||
|
|
LEN - given length of memory
