PCI Bus Interface
The MegaRAID controller interfaces to its host system through the PCI bus. The PCI bus
allows 32-bit high speed transfers and supports a burst data rate of over 130 MB per second.
AT Compatible BIOS
The MegaRAID controller has an Advanced Technology (AT) compatible BIOS containing a
set of special programs which receive control of the system when it is first powered on. The
MegaRAID controller then intercepts all INT13 BIOS calls and translates them into the
appropriate RAID control codes.
MegaRAID Controller Firmware
The MegaRAID controller firmware programs, stored on the flash EEPROM, are executed
by the i960 RISC processor. The flash EEPROM allows the system firmware to be upgraded
without replacing any hardware.
NOTE If the firmware becomes lost, contact the Customer Response Center for assistance. Only
qualified service personnel should update the firmware.
RAID SCSI Bus
The RAID SCSI bus connects the disk drives and internal devices to the MegaRAID
controller. The MegaRAID controller is Ultra Wide SCSI. The Ultra Wide SCSI feature is
enabled for InterRAID-8e.
