Endian Issues
The MTX series suppors both little-endian software (for example, NT) and
big-endian software (for example, AIX). Because the PowerPC processor
is inherently big-endian, PCI is inherently little-endian, and the VMEbus
is big-endian, things do get rather confusing. The following figures shows
how the MTX series handles the endian issue in big-endian and little-
endian modes:
