If you decide to reduce the swap partition of A/UX and use that freed disk
space for a Macintosh OS HFS file system, there are a number of things to
consider:
- You can reduce the size of the swap area with HD Setup (2.0). Select the
swap area, delete it, and create a new one of a smaller size. It contains
no useful data when A/UX is not running so you can safely ignore the
warning. As soon as you boot up A/UX, you also have to adjust the size
stored in the kernel, by entering in single user mode:
kconfig -n /unix
SWAPCNT=<New-swap-space-size-in-512-byte-units>
<Control-d>
Then reboot to make it effective. To permanently change this value--even
when reconfiguring the kernel, you also should change the "/newunix" file.
- There is no need to use either "dp" or "adb" for this if you use "Apple
HD SC Setup v2.0b12" or later, which includes partitioning.
- There can be only one HFS partition per disk under Macintosh OS.
- Once you have freed some of the disk space, you can increase the size of
the Macintosh OS partition as follows: back it up on floppies, delete it,
move partitions on the disk to make a large contiguous gap, create a new
HFS partition, and restore the floppies on the newly created partition.
Be prepared--moving partitions takes a lot of time since HD Setup copies
all its data.
