0x0001FE00? Where does that value come from?

I've always had the impression that 64K is a limit on some systems, so something like 0x0000FF00 would be logical (wouldn't make much of a performance difference anyway). Could someone enlighten me?

PS: didn't know about the 1200 IDE bug, my systems have always been 'pure SCSI'. ;-)

And based on past observations, I'm under the impression this is a signed value, so 0x7fffffff would be the max, anyway.


LOL - just show me an Amiga with a RAM amount just remotely close to that value and I'll gladly explain everything to you...  :crazy:  ;-)

:-P My point, of course, was that 0x80000000 = -1 [...]

Obviously you mean 0xFFFFFFFF = -1, 0x80000000 = -2^31

AFAIK there are numerous issues with invalid signed long usage in AmigaOS, so anything beyond 2 GB is out of the question. Actually I was trying to refer to a real Amiga that even with several DKB3128s (or extremely rare) upgraded Fastlanes is far below that mark. :-)
