I shouldn't have said rumor (and if @&&*&*^ news woulda let me cancel this...)

A letter to NuBus developers from Apple dated September 1 says a new
ROM is planned in November; new machines will get the ROM and dealers
will do a ROM upgrade on any serviced/upgraded machine.

The problem is the Slot Manager won't recognize cards with > 1 Megabyte
of memory (can you say "24-bit video card?") because it doesn't run
in 32-bit mode.  In the new ROM, the Slot Manager will run in 32
bit mode, according to the letter.

Today, only the lowest 1 Megabyte of address space of a NuBus card
is visible to the Slot Manager.  Since declaration ROM has to be at
the top of the address space, if it uses > 1 Megabyte, the declaration
ROM "disappears".  Neat, huh?

Apple says that card developers should notify their customers if their
product requires the new ROM; they will be providing a ROM version
application to see whether you need to visit your dealer.
