Dumbly following the HOWTO (which has a subtle bug) is not adviced: --- As a sidenote, I think the HOWTO/EPIA-M is wrong about how to extract: WRONG: dd if=/dev/mem of=/video.bios.bin \ WRONG: bs=1 count=65536 skip=790528 Note that 790528=0xC1000 and 65536=0x10000 /dev/mem must be read from 0xC000-0xD000 (VGA BIOS), whereas /proc/kcore must be read from 0xC1000-0xD1000 because kcore is an ELF 'view' to the memory, with a 0x1000 ELF header at 0xC000. What I did is extract from 0xC000-0xD000 as follows: dd if=/dev/mem of=/113mem.bin skip=1536 count=128 (bs=512 by default) ---</sidenote>--- leon at nehemiah <http://www.openbios.org/mailman/listinfo/linuxbios>:/$ ls -ald /113mem.bin -rw-r--r-- 1 root root 65536 2006-02-23 03:57 /113mem.bin leon at nehemiah <http://www.openbios.org/mailman/listinfo/linuxbios>:/$ hexdump -C /113mem.bin | head -n 10 00000000 55 aa 7d e9 26 7f 5e 1b fa f9 f4 82 00 00 00 00 |/U.}.&.^.........| /00000010 00 00 00 00 00 00 00 00 44 00 d4 b0 c6 00 49 42 |/........D.....IB| /00000020 4d 20 43 4f 4d 50 41 54 49 42 4c 45 42 43 50 4f |M COMPATIBLEBCPO| 00000030 53 54 00 00 18 00 30 34 2f 31 38 2f 30 33 01 15 |/ST....04/18/03..| /00000040 00 c0 c6 00 50 43 49 52 06 11 22 31 00 00 18 00 |/....PCIR.."1....| /00000050 00 00 00 03 40 00 51 01 00 80 00 00 00 01 20 20 |/.... at .Q....... <http://www.openbios.org/mailman/listinfo/linuxbios> | /00000060 20 56 49 41 20 54 65 63 2e 49 6e 63 2e 20 20 20 | VIA Tec.Inc. | 00000070 20 20 20 20 20 20 20 20 20 56 45 52 2e 56 54 33 | VER.VT3| 00000080 31 32 33 20 20 20 20 01 15 01 12 56 49 41 20 20 |123 ....VIA | 00000090 20 20 20 20 20 20 20 20 20 20 20 20 00 00 00 00 | ....| leon at nehemiah <http://www.openbios.org/mailman/listinfo/linuxbios>:/$ md5sum /113mem.bin 87017abc14c53e51a269fe59b5ba1508 /113mem.bin --- Regards, Leon. -- linuxbios mailing list [email protected] http://www.openbios.org/mailman/listinfo/linuxbios
