Some details can be parsed more accurately if 46 the platform is known. 47 48--panel-type=N 49 Parse the details for flat panel N. Usually this is retrieved from the Video 50 BIOS Tables, but this can be used to override. 51 52--all-panels 53 Parse the details for all flat panels present in the Video BIOS Tables. 54 55--hexdump 56 Hex dump the blocks. 57 58--block=N 59 Dump only the BIOS Data Block number N. 60 61REPORTING BUGS 62============== 63 64Report bugs to https://bugs.freedesktop.org. 65 66SEE ALSO 67======== 68 69**intel_bios_dumper(1)** 70
