Does anyone know what format Phoenix uses for their ROM bios extensions? I know the bios checks for an 8-bit checksum over the entire block and it expects a magic number of 0xaa55. The user docs say that the bios gets the size of the extension from the "extension header". From the 3 bios extensions that I have, it's not obvious where that size is stored or what the entry address is. 8-( I've tried asking (a) the board vendor (Intel); (b) the board manufacturer (Radisys); and (c) Phoenix. -- John Birrell - jb@cimlogic.com.au; jb@freebsd.org http://www.cimlogic.com.au/ CIMlogic Pty Ltd, GPO Box 117A, Melbourne Vic 3001, Australia +61 418 353 137 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
