It still booted with all 8G. :( But, changing it to addappend = " mem=4G" seemed to do the trick. And, your guess might be correct. I now see the correct messages for the MegaRAID: scsi 4:4:0:0: Direct-Access MegaRAID LD 0 RAID5 1430G N661 PQ: 0 ANSI: 2 sd 4:4:0:0: [sda] 2930307072 512-byte hardware sectors: (1.50 TB/1.36 TiB) sd 4:4:0:0: [sda] Write Protect is off sd 4:4:0:0: [sda] Mode Sense: 00 00 00 00 sd 4:4:0:0: [sda] Asking for cache data failed sd 4:4:0:0: [sda] Assuming drive cache: write through sd 4:4:0:0: [sda] 2930307072 512-byte hardware sectors: (1.50 TB/1.36 TiB) sd 4:4:0:0: [sda] Write Protect is off sd 4:4:0:0: [sda] Mode Sense: 00 00 00 00 sd 4:4:0:0: [sda] Asking for cache data failed sd 4:4:0:0: [sda] Assuming drive cache: write through sda: sda1 sd 4:4:0:0: [sda] Attached SCSI disk sd 4:4:0:0: Attached scsi generic sg1 type 0 Cheers, Eddie
