Slackware 13 Boot DVD doesn't recognize Adaptec 2005S RAID5 array
I'm attempting to upgrade a server from Slackware 10.2 to Slackware 13.0. When I boot with the Slackware 13.0 Install DVD, fdisk will not recognize the RAID5 array; it complains about being unable to seek on /dev/sda.
The system is a SuperMicro motherboard with onboard SCSI and an Adaptec 2005S Zero-Channel-RAID card; it works fine in Slackware 10.2 using the dpt_i20 driver.
Anyone have any suggestions?
