In order to install directly from the hard disk you must
have a partition with a directory containing the Slackware
distribution such that each disk other than the boot disk
is contained in a subdirectory. For example, if the 
distribution is in /stuff/slack, then you have to have
directories named /stuff/slack/a1, /stuff/slack/a2, and so
on each containing the files that would be on that disk.
You may install from DOS, HPFS, or Linux partitions.
Please enter the partition where the Slackware sources can 
be found, or [enter] to see a partition list: \n

Sorry, but the directory $SLACK_SOURCE_LOCATION does not exist
on partition $SLACK_DEVICE.

Would you like to try again?
