[comp.sys.apple] Booting /RAM5 from software

>> How to boot /RAM5 or any RAMdisk from software.

How about reading block 0 with a smartport call, loading up the registers
and jumping to $00/$0801?
I think X must be set to #%11010000 for /RAM5 but I can't remember off hand.
This will not stuff up your control panel settings ...
General code can be written to support any device with a ROM block driver
(ie: this sort of approach is more complex for a 5.25" - no driver in ROM).
It also will not do a reset - so much of memory and settings are not
changed (This may or may not be what you want!).
