Notes
- The Prestoserve requires minimum ISP-80 firmware 525-1023-05, 525-1024-08,
and 525-1025-08. Lower revisions of firmware may cause SunDiag to hang when
the ISP-80 is used with the Prestoserve and 2MB of memory. Systems with more
than 32MB are not affected.
- ISP-80 501-1539-08 and 501-1855-02 contain the minimum firmware required
by the Prestoserve
- Upgrade lower revision ISP-80 Controller boards with Option X2080A.
- The SS600MP supports one VMEbus or one SBus Prestoserve.
- VMEbus Prestoserve accelerates VMEbus disk controllers.
Battery Notes
- Set SW4 to BAT when the board is installed. Software will not initialize Prestoserve unless
battery backup is enabled.
- Set SW4 to 5V when the board is removed and cache data does not need to be preserved.
- Cache data is cleared from memory when SW4 is set to 5V for more than five minutes.
- The batteries are not field replaceable.
Release Notes
- The minimum operating system is SunOS 4.1 PSR A.
- The minimum operating system for the SS600MP is Solaris 1.0.1.
- The VMEbus Prestoserve is not supported on Solaris 2.2.
- Under Network CoProcessor release 1.4, the VME address space of the Prestoserve and the
fifth NC400 board is at 0x800000. If both Prestoserve (pr0) and a fifth NC400 (ne4) are
installed, change the address of pr0 to 0xc00000 on the Prestoserve board and in the kernel.
This restriction does not apply to Network CoProcessor release 1.4.
When the Prestoserve is set to 0xc00000, the alternate 24-bit settings or the NC400 at 0xc00000 - 0xc7ffff and 0xc80000 - 0xcfffff cannot be used.
When the Prestoserve is set to 0xc00000, the address space, 0xc00000 - 0xcfffff, reserved for large OEM/user devices is used.
