Abstract
A method for utilizing a multi-channel SCSI chip capable of controlling different types of devices is disclosed. A first channel control is set and a second channel control is set in the SCSI chip. A first peripheral device type is managed using the first channel control and a second peripheral device type is managed using the second channel control.
Claims27
A method for utilizing a SCSI chip capable of controlling different types of devices, comprising:
- setting a first channel control in the SCSI chip, wherein the first channel control is a RAID channel control;
- setting a second channel control in the SCSI chip, the second channel control being a SCSI channel control,
- wherein the setting the first channel control in the SCSI chip and setting the second channel control in the SCSI chip includes:
- communicating with a system BIOS to establish access to a CMOS programming instruction;
- managing a first peripheral device type using the first channel control;
- and
- managing a second peripheral device type using the second channel control.
A dual channel SCSI chip capable of controlling different types of peripheral devices, comprising:
- a first channel, the first channel for managing a first peripheral device, wherein the first channel is configured to contain a first configuration register;
- a second channel, the second channel for managing a second peripheral device, wherein the second channel is configured to contain a second configuration register;
- a first interrupt, the first interrupt being configured to connect with the first channel;
- a second interrupt, the second interrupt being configured to connect with the second channel;
- and
- an arbiter, the arbiter being configured to control access by the first channel and the second channel to a memory having configuration information for the dual channel SCSI chip.
A method for utilizing a SCSI chip capable of controlling different types of devices, comprising:
- setting a CMOS programming instruction in a memory;
- rebooting a computer to initialize the computer based on the CMOS programming instruction;
- communicating with a system BIOS to establish access to the CMOS programming instruction;
- determining a SCSI chip configuration by examining the CMOS programming instruction;
- writing a first device ID's to a first SCSI chip channel;
- and
- writing a second device ID's to a second SCSI chip channel.
A method for configuring a SCSI chip capable of controlling different types of devices, comprising:
- setting a CMOS programming instruction in a memory;
- rebooting a computer to initialize the CMOS programming instruction into a memory;
- determining a SCSI chip configuration by examining the CMOS programming instruction;
- writing a first device ID's to a first SCSI channel;
- and
- writing a second device ID's to a second SCSI channel;
- wherein the determining the SCSI chip configuration by examining the CMOS programming instruction includes checking Gattling bits from the memory to establish types of devices the SCSI chip is required to control.
