It was Tim Patterson who decided spliting that 1MB into 384KB for the system and 640KB for the user was enough. And Bill Gates, famously, agreed with him.Sweet, good old memory expansion cards for EMS. IBM thought that 640KB was enough for any desktop users.

just brew it! wrote:Yes, the appetite for memory will always be unbounded. Fortunately, despite the present transitional hiccups, the (current) 48bit virtual address space and (easily-extended) 40bit physical address space will last us for a long time. The IPv6 transition is the real new frontier.It's kind of funny how things never really change. Not enough physical address space... reserved addresses for video cards and other peripherals getting in the way... hokey address bank swapping schemes to extend the life of the platform. We went through it in the 16-bit MS-DOS days with the 1MB barrier, and before that in the 8-bit days with the 64K barrier. Now we're doing it all over again with the 4GB barrier.

SuperSpy wrote:It is. That's why I wrote "(current)" and "(easily-extended)". In fact the 40bit physical address limit isn't even common to all past and present 64bit implementations.Not to take this too far off topic, but I thought the current limit was actually 64-bit (as in all the pointers and registers are 64 bits wide), and the 48-bit virtual and 40-bit physical address space was just the limit on the current implementations in x86-64 chips?

West of the House
You are standing in an open field west of a white house, with a boarded
front door.
There is a mailbox here.
