1This is a very simple COMBOOT program which can be used to dump memory 2regions over a serial port. To use it, type on the SYSLINUX command 3line: 4 5memdump <port> <prefix> <start>,<len> <start>,<len>... 6 7For example: 8 9memdump 0 funnysystem- 0,0x600 0x9fc00,0x400 0xf0000,0x10000 10 11... dumps three memory ranges (the standard BIOS memory ranges, often 12useful) onto serial port 0. The <port> can either be in the range 0-3 13for the standard BIOS serial port, or the I/O address of the UART. 14 15The data is transferred using the YMODEM protocol; the Unix 16implementation of this protocol is called "rb" and is part of the 17"lrzsz" (or "rzsz") package. If one uses a terminal program like 18Minicom, there is often a way to invoke it from inside the terminal 19program; in Minicom, this is done with the Ctrl-A R control sequence. 20
