vme_manual_setup, sys_attrs_vba_vipvic - Describes how to
set up VIP/VIC-based Alpha VME systems for use on the VMEbus,
including how to modify attributes of the vba_vipvic
kernel subsystem
VMEbus setup allows you to run the operating system on the
following VIP/VIC-based AXPvme and Alpha VME systems:
AXPvme single-board computers (SBCs)
Alpha VME 4/224 and 4/228 SBCs
Alpha VME 5/352 and 5/480 SBCs
Alpha VME 2100 system
For information about installing the operating system on
the listed systems, see the Installation Guide.
For information about setting up UNIVERSE II-based Alpha
VME systems for use on the VMEbus, see the
sys_attrs_vba_univ(7) reference page.
See System Configuration Supplement: OEM Platforms for
detailed information about the use of the VMEbus on the
listed systems, including the following topics: Configuring
the vba_vipvic subsystem Configuring VMEbus A32 and
A24 address spaces Configuring the VMEbus A16 address
space Configuring VMEbus interrupts Using VMEbus hardware
byte-swapping modes Sharing memory between big endian and
little endian processors Performing VMEbus slave block
transfers Performing VMEbus master block transfers with
local DMA Using the realtime interrupt-handling routine
rt_post_callout
The defaults supplied for various VMEbus parameters are
listed below. The default values specified should provide
proper VMEbus operation for most applications. Be careful
when modifying these values; not all adapters support all
fields.

A24_A32_Ovrlap 1 Inbound A24/A32, if same
space, overlap
The following VMEbus interrupt parameters provide initial
defaults that are later overwritten by system priority
level (SPL) values supplied by the platform. See the values
listed in System Configuration Supplement: OEM Platforms,
or query the values at run time using the command
sysconfig -q vba_vipvic.
