SUMMARY: VME boards & 600MP

[ It is possible that this message will be send twice ; I apologize]

Last week, I have asked Sun-Managers about the status ("unsupported",
"don't work") of the SCSI & Ethernet VME boards for the 670MP

Here are the results:

VME SCSI board (Sun-3 SCSI) : Will not work, since the SCSI driver
        in a 600MP is a "SCSA" (Sun Common SCSI Architecture) driver.
        The si driver for the Sun3 SCSI board don't seem to be
        SCSA compliant (according to Hal Stern)

VME Ethernet board: Will not work because there is no driver shipped
        with 4.1.2.

Everybody says that these boards have poor performance.
Everybody advises me to buy the new SCSI/EThernet SBUS card, which
is (at least for Ethernet) "3-8 times faster" (According to Hal Stern).
I will do...

IMPORTANT: The old Ethernet SBUS card will not work!!!!!

The Interphase ne board will not work "as it". You will need
new driver for sun4m architecture (It seems that the driver exists,
since Sun says that this board is supported)

The VME memory board of the 4/470 will not work. 600MP's memory are

The SMD VME board will not work.

Prestoserve 2.3 will work.

IPI VME will continue to work (Somebody told me "only the newer
part number) ; Does it mean IPI-2 only ????

In facts, for most of the "unsupported boards", hardware would work,
but SunOS 4.1.2 doesn't have the drivers. Copying .o files will
probably don't work, since 600MP architecture is "sun4m".

Thank's to everybody who answer :
