These comfortably take additional files.</p><p>FAT32 is technically superior, with the variable-length root directory, but for DASD volumes whose whole purpose is to contain a couple of tens of boot loader files it's not much of a practical advantage here. And indeed on the downside, the FATs are an order of magnitude bigger.</p><p><a href="https://mastodonapp.uk/tags/OpenBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenBSD</span></a>'s FAT16 partition in contrast is a tiny 8MiB. <a href="https://mastodonapp.uk/tags/TianoCore" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>TianoCore</span></a> UEFI firmware, approximately 4MiB, does not fit on it without deleting stuff.</p><p>Ironically, it is preceded by twice that amount, 16MiB, in free space not allocated to any partition. It's possible to delete the 8MiB Microsoft partition and re-create a 23MiB one, as long as one saves and restores the contents.</p><p><a href="https://mastodonapp.uk/tags/UEFI" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>UEFI</span></a> <a href="https://mastodonapp.uk/tags/DASD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DASD</span></a> <a href="https://mastodonapp.uk/tags/PartitionTables" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PartitionTables</span></a> <a href="https://mastodonapp.uk/tags/RaspberryPi" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RaspberryPi</span></a></p>
