Hi, The new bios.c fails on my Tyan S1563D with the Award 4.01 bios. The table retrieved with dd ibs=16 skip=57344 if=/dev/mem | hexdump -C | more looks like (results offset 0xe0000): 00015d10 5f 44 4d 49 5f 05 ff 02 00 10 0f 00 23 00 20 49 |_DMI_.......#. I| 00015d20 4d 44 24 23 00 49 00 67 8e 45 16 bf 1f 5d 26 81 |MD$#.I.g.E...]&.| It looks like the Award bios incorrectly assigns the trailing pad bytes. Also the 0x20 at 0x15d1e must be included in the checksum for a zero result. dave adkins
