some notes on coreboot in combination with NetBSD

New page

This page documents coreboot usage with NetBSD. It is probably terser than it could be, as it mostly just describes differences from the more-commonly-documented Linux procedures.

== building coreboot on NetBSD ==
GNU make is required to build coreboot, install it from pkgsrc/devel/gmake.
=== coreboot v2 ===
As of revision 3363 only one change needs to be made.

On NetBSD libintl is required to build kconfig.

== building [[LegacyBIOS]] on NetBSD ==
A change is required to '''legacybios/Makefile''', then gmake can be used to build LegacyBIOS in the normal way.

== booting NetBSD/x86 with coreboot ==
=== interrupt routing ===

Legacy interrupt routing (the PCI interrupt line register) is traditionally not
implemented on many mainboards under coreboot. MPBIOS or ACPI will be required.

NetBSD does not (without patching) search for a MPBIOS floating pointer at the location
coreboot usually places it. LegacyBIOS does relocate this pointer structure however.

=== BIOS calls ===
NetBSD/i386 GENERIC still makes some BIOS calls after boot(8):
* isapnp(4)
* mca(4)

Removal of these subsystems from your kernel config(5) file removes these calls.

Due to the nature of x86_64, BIOS calls on NetBSD/amd64 are not a problem, as they cannot be made from long-mode.
