biosdecode<\/b> [OPTIONS<\/b>]<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

biosdecode<\/b> parses the BIOS<\/small> memory and prints information about all structures (or entry points) it knows of. Currently known entry point types are:<\/p>\n\n\n

biosdecode<\/b> started its life as a part of dmidecode<\/b> but as more entry point types were added, it was moved to a different program.<\/p>\n

OPTIONS <\/a> <\/h2>\n

-d<\/b>, –dev-mem FILE<\/b><\/p>\n

Read memory from device FILE<\/b> (default: \/dev\/mem<\/b>)<\/p>\n

–pir full<\/b><\/p>\n

Decode the details of the PCI IRQ routing table<\/p>\n

-h<\/b>, –help<\/b><\/p>\n

Display usage information and exit<\/p>\n

-V<\/b>, –version<\/b><\/p>\n

Display the version and exit<\/p>\n

FILES <\/a> <\/h2>\n

\/dev\/mem<\/i><\/p>\n

BUGS <\/a> <\/h2>\n

Most of the time, biosdecode<\/b> prints too much information (you don\u2019t really care about addresses) or not enough (because it doesn\u2019t follow pointers and has no lookup tables).<\/p>\n
