Minix needs one primary partition of at about 210 MB for a full install

with sources. (The full install also fits in about 180 MB, but it

needs more if fully recompiled. Add more space to taste.)

it bigger.

If there is no free space on your disk then you have to back up one of the

other partitions, shrink, and reinstall. See the appropriate manuals of the

the operating systems currently installed. Restart your Minix installation
|

after you have made space.

advice under the '!' key to make a new partition of type MINIX. Do not

touch an existing partition unless you know precisely what you are doing!

Please note the name of the partition (e.g. c0d0p1, c0d1p3, c1d1p0) you

make. (See the devices section in usage(8) on Minix device names.)
