>From 2.4.13 Configure.help: HPT366 chipset support CONFIG_BLK_DEV_HPT366 HPT366 is an Ultra DMA chipset for ATA-66. HPT368 is an Ultra DMA chipset for ATA-66 RAID Based. HPT370 is an Ultra DMA chipset for ATA-100. [snip] So it seems that the HPT368 RAID controller is supported - even if not in RAID mode. >From 2.4.13 drivers/ide/Config.in: dep_tristate 'Support for IDE Raid controllers' CONFIG_BLK_DEV_ATARAID $CONFIG_BLK_DEV_IDE $CONFIG_EXPERIMENTAL dep_tristate ' Support Promise software RAID (Fasttrak(tm))' CONFIG_BLK_DEV_ATARAID_PDC $CONFIG_BLK_DEV_IDE $CONFIG_EXPERIMENTAL $CONFIG_BLK_DEV_ATARAID dep_tristate ' Highpoint 370 software RAID' CONFIG_BLK_DEV_ATARAID_HPT $CONFIG_BLK_DEV_IDE $CONFIG_EXPERIMENTAL $CONFIG_BLK_DEV_ATARAID There's no help for the above (I recall there was in one of the -ac kernels). They allow Linux software RAID to do the same thing as the BIOS software RAID in those adapters. Having software RAID in the BIOS match software RAID in Linux will solve some boot problems and does offer benefits over a straight Linux software RAID solution. Setting it up properly with the boot loader will be tricky though (setting it up to basically boot will be easy). -- http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/projects.html Projects I am working on http://www.coker.com.au/~russell/ My home page
