The Question is:
Can you run OpenVMS on a DEC PWS 500a that has an EIDE CDROM, Qlogic SCSI
controller and DEC SCSI hard drive?
System has latest firmware and the bios can be changed to Alphabios, SRM True64
and SRM OpenVMS.
The Answer is :
There is no support for OpenVMS on this or any other member of the
Personal Workstation -a (PWS-a) series, as previously referenced
here and as is mentioned in the OpenVMS Frequently Asked Questions
Again, the PWS-a series is not supported.
No member of the Personal Workstation -a series is supported.
OpenVMS is not supported on any Microsoft Windows NT (only) Alpha
No so-called whitebox Alpha system is supported by OpenVMS.
The PWS -au series is supported by OpenVMS.
There is no official nor sanctioned mechanism to convert a Personal
Workstation -a system into an -au series system.
For further information and the official list of supported platforms,
please see the Software Product Description (SPD) for OpenVMS.
As with any unsupported configuration, you might or might not be
able to get OpenVMS to bootstrap and operate in the configuration,
and (assuming it bootstraps) OpenVMS might or might not be stable,
and specific OpenVMS features might or might not operate as expected.
As with any supported or unsupported Alpha platform, use of the
latest SRM console firmware is recommended.
The OpenVMS FAQ also has discussions of ATA (IDE) CD-ROM device
bootstraps that are applicable to various members of the Personal
Workstation series platforms. Search the text-format version of
the OpenVMS FAQ for the string Cypress for details on this.
