This document, "DIGITAL AXPpci33 Firmware Update Procedures," provides instructions for updating the system firmware on DIGITAL AXPpci33 series computers. These systems utilize two flash ROMs that can be programmed with either ARC console firmware (for Windows NT operating systems) or SRM console firmware (for DIGITAL UNIX operating systems), with compatibility details for various OS versions provided.
The primary method of updating firmware involves using a Firmware Update Utility Compact Disc. Detailed, step-by-step procedures are provided for:
auto_action environment variable to HALT, booting from the utility disk, executing the update srm command, verifying the checksum, and power cycling the system.update arc and verification. The document also highlights specific problems encountered during Windows NT updates, such as issues with CD search paths (requiring floppy use for older firmware versions), display device configuration affecting output, and potential hangs with bridged PCI cards (which may need temporary removal).The document also outlines procedures for Network and InfoServer Upgrades, which are supported primarily for DIGITAL UNIX systems running SRM firmware:
/etc/bootptab and /etc/tftptab files on a host system, invoking bootpd and tftpd daemons, and then booting the target from the network.Finally, the guide details DIGITAL AXPpci33 Series Firmware Information, noting that the current release primarily offers bug fixes without new functionality. It also lists several SRM Firmware Limitations, including potential IRQ resource conflicts, requirements for quoting boot file pathnames, issues with ISACFG command modifications (which require device removal and re-addition to correct), CD-ROM boot timeout errors, specific generic BOOTP setup commands, and a console bug during DIGITAL UNIX installations that obscures commands needed for setup, requiring manual intervention.
