The MVME7100 uses a TSi148 for its PCI/X-to-VME bus bridge. The offsets of the mailboxes
in the TSi148 are defined in the TSi148 VMEBus PCI/X-to-VME User Manual, listed in
Appendix B, Related
Mailbox 0 is at offset 7f610 in the CR/CSR space
Mailbox 1 is at offset 7f614 in the CR/CSR space
Mailbox 2 is at offset 7f618 in the CR/CSR space
Mailbox 3 is at offset 7f61C in the CR/CSR space
The selection of the mailbox used by remote start on an individual MVME7100 is determined
by the setting of a global environment variable (GEV). The default mailbox is zero. Another GEV
controls whether remote start is enabled (default) or disabled. Refer to the Remote Start
appendix in the MOTLoad Firmware Package User's Manual for remote start GEV definitions.
The MVME7100's IBCA needs to be mapped appropriately through the master's VMEbus
bridge. For example, to use remote start using mailbox 0 on an MVME7100 installed in slot 5,
the master would need a mapping to support reads and writes of address 0x002ff610 in VME
CR/CSR space (0x280000 + 0x7f610).

Boot Images
Valid boot images whether POST, USER, or Alternate MOTLoad, are located on 1 MB
boundaries within the upper 8 MB of flash. The image may exceed 1 MB in size. An image is
determined valid through the presence of two "valid image keys" and other sanity checks. A
valid boot image begins with a structure as defined in the following table:
