20 Outline

Some platforms have features which allows to implement some commands useless or not implementable on others.

Quick summary:

Information retrieval:

• mipsel-loongson: lsspd
• mips-arc: lsdev
• efi: lsefisystab, lssal, lsefimmap, lsefi
• i386-pc: lsapm
• i386-coreboot: lscoreboot, coreboot_boottime, cbmemc
• acpi-enabled (i386-pc, i386-coreboot, i386-multiboot, *-efi): lsacpi

Workarounds for platform-specific issues:

• i386-efi/x86_64-efi: loadbios, fakebios, fix_video
• acpi-enabled (i386-pc, i386-coreboot, i386-multiboot, *-efi): acpi (override ACPI tables)
• i386-pc: drivemap
• i386-pc: sendkey

Advanced operations for power users:

• x86: iorw (direct access to I/O ports)

Miscelaneous:

• cmos (x86-*, ieee1275, mips-qemu_mips, mips-loongson): cmostest (used on some laptops to check for special power-on key), cmosclean
• i386-pc: play
