For VAX/Alpha code from VMS, .sys would be an executable linked /NOHEADER. This would be a raw memory image; no ISDs or compression, just bits.
In this case, it appears to be a SRM console image that was extracted from an HP firmware update kit. The header is used by the firmware update utility and by the SRM's show version (IIRC). There's no reason for this to be loaded via MOP, at least on real hardware; SRM contains the MOP client. FYI, when qemu was working on alpha emulation, they applied some patches to that image - I have no clue what they do or why.
