For further details on CR/CSR space, please refer to the VME64 Specification, listed in Appendix B, Related Documentation.

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 Documentation, but are noted here for reference:

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).

6.7Boot 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:
