	Has anyone booted the 5.0 distribution off a 11/750 with an Eagle,
SC750 and a TS11 ?
	The root filesystem seems to load but the boot program flutters
and doesn't load UNIX. Its probably a case of an imperfect emulation. I had
the SC750/Eagle set for RM80 emulation.
	Presumably the driver thinks its an RM80 with 31 sector tracks and
the Eagle/SC750 has 47 sector tracks. So it must be a constant where that I
can patch.
	Any ideas ?
						Thanks.

Speaking of Emulex controllers, I have seen a similar problem where the 
SC780/9766 combination doesn't QUITE look like an rm05. VMS and VMS diagnostics
seem quite happy with the drive, but the System V boot block acts quite 
confused.

I wouldn't be suprised if it's an imperfect emulation, with timing being the
problem. (A friend saw such timing problems on an 11/70 Emulex controller.)
Has anyone else seen this?
