Adaptec RAID Installation Guide
Zero Channel RAID Controllers (2000S, 2005S)
The Adaptec RAID controllers 2000S and 2005S have unique
installation requirements. These controllers are Zero Channel RAID
(ZCR) cards and work with the motherboard’s embedded Adaptec
SCSI chip to provide advanced RAID functionality. SCSI devices
may be connected to the system prior to installation of the
ZCR.Under these conditions, the user should back-up any data on
the disk drives prior to implementing a ZCR solution.
Note: If data exists on drives before implementing RAID,
backup data prior to installing RAID controller as data will
be lost during RAID creation.
The Adaptec 2000S controller has a standard 64-bit, 3.3v PCI
interface but will only function properly when inserted into a PCI
slot supporting Adaptec Embedded RAID Logic (EMRL) or Intel
RAIDIOS™ logic. The 2005S controller has a unique design and
plugs into a special EMRL enabled SO-DIMM socket provided on
specific motherboards.
To install your ZCR controller, insert the device into the supported
ZCR enabled slot on the motherboard (consult your system's
documentation for the supported slot(s)). Load the driver associated
with the system's operating system as described in this guide. To
ensure proper installation, examine the system's screen during
system boot. Instead of showing an Adaptec SCSI BIOS message,
the system will display an Adaptec I
2
OBIOS message indicating the
results of its SCSI scans and RAID device creation.
Determining the Booting Controller
Adaptec RAID controllers are shipped with a controller BIOS ROM
enabled for PCI assignment. This BIOS intercepts and processes
Int13 BIOS calls with an embedded DOS driver.
The controller BIOS ROM can be disabled or the address changed
automatically by the system’s Plug-and-Play BIOS. In systems with
multiple Adaptec controllers, the first Adaptec RAID controller
found during boot loads its BIOS and installs all of the other
Adaptec controllers. Any additional Adaptec RAID controllers that
