There are no roms for classic systems required. You can get 4.0 for classics with PPC accelerators in software form (CD-ROM) but no 4.1.

I think they're too big to fit in standard Amiga (EP)ROMs

i do belive the extra pins on A1200 rom socket ( not used )is for 1MB roms ( correct me if im wrong ) i will look at the doc again.

this will be a sure way to find out if this is true.

I recall that Hyperion and Individual Computers (was it?) announced many years ago some kind of a "kick flash OS4" thing or whatever, that would be required to boot OS4 (some kind of dongle feature in a way) and also boot directly into the new OS. Obviously it didn't happen that way though...

It was replaced in a way by the open firmware Uboot, which it wont boot without

Though not on classics

I dont believe anyone ever really tried to use Piru exec and 1Mbyte OS3.9 ROMS. Motorollin made 512Kbyte OS3.9 ROM's

IIRC from the specification sheet that came with my A1200, there was up to 4 MiB addressing devoted to ROM meaning there would be two banks of 2 MiB for ROM usage.  I don't know of it ever being used as such however.

is there anyway i can get OS4 on 1MB kickstart roms the legal way?

if someone else done this for me will it lead to legal/copyright problems?

also is is possibe to access Blizzard PPC menu after OS4 kickstart has loaded?
