MINIX needs one primary partition of about 250 MB for a full install.
|
|
The maximum fill system currently supported is 4 GB.
|
|
|
|
If there is no free space on your disk then you have to choose an option:
|
|
(1) Delete one or more partitions
|
|
(2) Allocate an existing partition to MINIX 3
|
|
(3) Exit setup and shrink a partition using a different OS
|
|
|
|
To make this partition you will be put in the editor \"part\". Follow the
|
|
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.)
