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.
HPT372 is an Ultra DMA chipset for ATA-133.
HPT374 is an Ultra DMA chipset for ATA-133.
 
This driver adds up to 4 more EIDE devices sharing a single
interrupt.
 
The HPT366 chipset in its current form is bootable. One solution
for this problem are special LILO commands for redirecting the
reference to device 0x80. The other solution is to say Y to "Boot
off-board chipsets first support" (CONFIG_BLK_DEV_OFFBOARD) unless your mother board has the chipset natively mounted. Regardless one should use the fore mentioned option and call at LILO or include "ide=reverse" in LILO's append-line.
 
This driver requires dynamic tuning of the chipset during the
ide-probe at boot. It is reported to support DVD II drives, by the manufacturer.

CONFIG_BLK_DEV_ATARAID_HPT:
 
Say Y or M if you have a Highpoint HPT 370 Raid controller
and want linux to use the softwareraid feature of this card.
This driver uses /dev/ataraid/dXpY (X and Y numbers) as device
names.
 
If you choose to compile this as a module, the module will be called hptraid.o.

Multiple devices driver support (RAID and LVM)
