You want to install Slackware 9.0 using floppy disk?
Here's what you should do.
1.) Go in the BOOTDISKs folder and get bare.i, if that's the one you want.
For example, to use RAWRITE.EXE to create the
bare.i bootdisk you'd put a formatted disk in your floppy drive and issue the following command:
C:\> RAWRITE BARE.I A:
2.) Then go in the ROOTDISKS folder and get two files, Install.1 and Install.2.
For example, to make the first rootdisk image (install.1),
you'd put a formatted 1.44MB floppy in your floppy drive, and then run this command:
C:\> RAWRITE INSTALL.1 A:
and repeat for INSTALL.2 disk
Hopefully this should get you going.
If you want the boot/root disk again, try here
