About FastTrak100 TX/LP Series Disk Array Adapter
FastTrak100 is a high performance Ultra ATA/EIDE RAID controller card that features
concurrent data channel operation and an onboard BIOS. The channels on the
FastTrak100 support concurrent operation that allows for overlapped I/O under multi-
tasking operating systems and sharing the workload between multiple drives.
About Adapter BIOS
The FastTrak100 card contains a BIOS code that extends the standard disk service
routine provided through Int13. The BIOS is bootable for DOS and other operating
systems that rely on the system BIOS for drive operation. When the FastTrak100
TM
BIOS appears during bootup, users can press <F2> to enter the FastBuild
setup to
select from menu settings.

FastBuild
Auto Menu Setup
This setup utility is used to build and manage FastTrak100 disk arrays. The utility is
menu driven and features the <1> Auto Setup option that uses a simple, interactive
setup process. Once the array is built, all the array members store the configuration
information in the drive's reserved area. See Chapter 4, which provides descriptions
of individual functions.
Reserved Sector
Array configuration data about the drive member and other members in the disk array
are saved on a special location on the disk drives called the reserved sector. If any
member of the array becomes corrupt or lost, the redundant configuration data on the
other members can be used for rebuilds.
Disk array members do not have a "memory" of their drive positions. This allows
drives to be placed on different FastTrak100 connectors or cards within the system
without reconfiguring or rebuilding.
