For Lenovo laptops with buggy bios (x220, t420, t520):
Write the 0xee entry into the second slot in the pmbr instead of the first
For some Dell and HP models:
The BIOS gives a warning message when booting in legacy mode from a GPT partitioned disk where the 0xee partition in the pmbr is not flagged active
For models known to have this problem, mark the pmbr active during installation
Use smbios data to identify machines known to be affected by any of the above, and offer the user the option to apply the workaround
In bsdinstall's ufs auto mode (autopart partition wizard):
Allow users to select which type of partition table to use
Keep current defaults: MBR for BIOS, GPT for UEFI
This allows users to choose GPT for legacy boot if they wish

a sysctl to determine what firmware is in use. This sysctl does not exist
yet, so the following blocks are in front of the wheels:
- I've provisionally called this "hw.platform" after the equivalent thing
on PPC
- The logic to check the sysctl is short-circuited to always choose BIOS.
There's a comment in the top of the file about how to turn this off.
If IA64 acquired a boot1.efifat-like thing (probably with very few
modifications), the same code could be adapted there.

bsdinstall scriptedpart 'ada0 GPT {1.5G freebsd-ufs /, 10G freebsd-swap,
auto freebsd-ufs /usr}'
to set up a system with a 1.5GB /, some swap space, and a /usr using the
rest of ada0.

pc-sysinstall) a replacement for sysinstall in the 9.0 release and beyond.
Currently supported platforms are sparc64, pc98, i386, amd64, powerpc, and
powerpc64. Integration into the build system will occur in the coming
weeks.
Merging with pc-sysinstall will use this code as a frontend, while
temporarily retaining the interactive partition editor here. This work
will be done in parallel with improvements on this code and release
integration.
Thanks to all who have provided testing and comments!
