Configuring the ataraid Driver
After your system is up and running with the FastTrak driver, I recommend converting to the ataraid driver for increased stability and performance. If you are only adding a Promise controller to an existing system, start with the steps in this section.
Native support for Promise RAID controllers is located in the ATA/IDE/MFM/RLL Support section of the Linux kernel configuration. First enable Development Support because the ataraid driver is still experimental. Then enable the following features:
<*> ATA/IDE/MFM/RLL support
IDE, ATA and ATAPI Block devices --->
<*> Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support
...
<*> Include IDE/ATA-2 DISK support
...
[*] Generic PCI IDE chipset support
...
[*] PROMISE PDC202{46|62|65|67|68} support
[*] Special UDMA Feature
[*] Special FastTrak Feature
...
<*> Support for IDE Raid controllers
<*> Support Promise software RAID (Fasttrak(tm))Once you have enabled support for the preceding options, execute make and copy the new kernel into your /boot directory:
#make dep && make bzImage#make modules && make modules_install#cp arch/i386/boot/bzImage /boot/bzImage.ataraid
Reconfiguring LILO
Versions of LILO earlier than 22 do not recognize ataraid devices. So you will have to upgrade LILO before executing /sbin/lilo to update the boot sector of a Promise array that uses the ataraid driver. Use the command lilo -V to determine which version of LILO you are using. If necessary, download the latest version of LILO from ...
