OpenVMS and Personal Workstation ATA (IDE) bootstrap?
OpenVMS will boot and is supported on specific Personal Workstation -au series platforms, though OpenVMS will require a SCSI CD-ROM if the Intel Saturn I/O (SIO) IDE chip is present in the configuration- only the Cypress IDE controller chip is supported by OpenVMS for IDE bootstraps. (Configurations with the Intel SIO are not generally considered to be supported systems.) If you have an -au series system, you can determine which IDE chip you have using the SRM console command: SHOW CONFIGURATION If you see “Cypress PCI Peripheral Controller”, you can bootstrap OpenVMS from IDE storage. If you see “Intel SIO 82378”, you will need to use and bootstrap from SCSI. (A procedure to load DQDRIVER on the Intel SIO- once the system has bootstrapped from a SCSI device-is expected to be included as part of the contents of the DQDRIVER directory on Freeware V5.0 and later.) Many of the -a series systems will include the Intel SIO, and thus cannot bootstrap from IDE. See Section 14.4.4 for related
