Two different patch disks exist and they are not interchangeable:
- 2.1p2a (Commodore) — the official patch. This is the one to use for a normal tape install. Brings the kernel to 2.1c.
- 2.1 patch disk (oddsocks, 2013) — for the hard-disk-install hack. Not applicable here.
See https://www.amigaunix.com/doku.php/patch-disk.
Insert the 2.1p2a disk, follow its instructions, then:
shutdown -i6
Everything including networking should come back up. Confirm:
$ uname -a
UNIX_System_V amix 4.0 2.1c 0800430 Amiga (Unlimited) m68k
Snapshot again once verified.
APFS clones make these effectively free:
cd ~/Documents/FS-UAE/AMIX
cp -c a3000ux.hdf a3000ux-2.1c-patched.hdf
To restore, rename the live file aside first rather than letting cp
truncate in place, so a mid-copy failure cannot damage the snapshot:
mv a3000ux.hdf a3000ux-old.hdf
cp -c a3000ux-2.1c-patched.hdf a3000ux.hdf
