When booting from the Beta 2 CD-ROM, the aacraid driver is not present in the installer image modules.cgz, module-info, or pcitable files. This is a new driver, required for Dell PowerEdge on-board and add-in RAID controllers. The driver is present in the 2.2.16-3 kernel. The module must simply be added to the various installer types (CD-ROM, hard disk, and network).
Still an issue in Beta 3.
Driver disk uploaded to ftp.beta.redhat.com/pub/incoming/aacraid-dd-beta3.img.
Aargh! The entry was missing in the module-info, that made it be dropped off the disk. So many apologizes. Fixing now.
Fixed.
Driver is present in Winston Beta 4 CD, but may require expert install. Investigating and submitting as a separate issue.
