New features in Limine 3.11

July 11, 2022 — BarryK

In the Limine menu, you can have an entry to chainload to a drive with an MBR (MSDOS partition table). Previously, the entry looked like this:

:MBR Chainload

The problem with that is we cannot guarantee what drive 1 is. Each drive in the computer is numbered, starting from 1, but the boot drive is not necessarily number 1.

To get around this uncertainty, MBR drives do have something called a "partition table UUID", that you can discover like this:

# lsblk --pairs -o PTUUID --nodeps /dev/sdb

I discussed this with mintsuki:

And now there is a new parameter:

:MBR Chainload

...this guarantees the correct drive will be chainloaded.

If you have, say grub4dos, installed on that drive, it will startup in the normal way and display its menu.

The second new feature resulted from discussion here:

Menu entry:

:Chainload next drive

Here is the commit:

Actually, I'm not 100% sure what it will do. I will have to play with it.
