The above-referenced URL states "Now Enhanced with Streamlined Installation, Unique Online Software Updates and New Systems Manageability Features". That statement is quickly revealed to be a crock when a PCMCIA installation on a laptop requests a THIRD floppy (the driver disk). The location of this disk image is not immediately apparent from scanning the RedHat 6.1 images/ directory. Also, I hope you finally have added a utility to compile an authoritative list of rpms necessary to upgrade the packages of an existing installation.
Ummm, pcmcia requires *1* disk, pcmcia.img. When you use expert mode, it will ask you for additional driver disks, as that is one of the added things in expert mode to let hardware vendors ship driver disks with their hardware if it is released after the 6.1 release.
This problem appears to be resolved.
