Linus Groh 5ee9aab7e1 Meta: Bump BIOS/MBR boot partition size of grub disk image to 1MiB
As of ~April 2021 the Meta/build-image-grub.sh script no longer works
for me (on Fedora 34) and fails with the following error:

    /usr/sbin/grub2-install: warning: ../grub-core/partmap/msdos.c:403:
    your core.img is unusually large. It won't fit in the embedding
    area.

    /usr/sbin/grub2-install: warning: Embedding is not possible. GRUB
    can only be installed in this setup by using blocklists. However,
    blocklists are UNRELIABLE and their use is discouraged..

    /usr/sbin/grub2-install: error: will not proceed with blocklists.

Changing the size of the boot partition from 32 kiB to 1 MiB (2048
sectors) fixes the issue. This is also described in the following Ubuntu
grub2 bug (as well as 40 duplicates!) from 2012, which suggests the same
fix: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1059827

The Arch Linux wiki also uses 1 MiB in their BIOS/MBR examples for
parted: https://wiki.archlinux.org/title/Parted

I'm not sure why this suddenly stopped working, however I was able to
boot with an image created with this change applied.

SerenityOS

Graphical Unix-like operating system for x86 computers.

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
