## 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
