Following up to my own post... I think the problem with '1.44 Mb' is that IBM chose to refer to the exact number of bytes without using the power-of-two term properly. For example... on pdp-11s, the virtual address space is always referred to as 64 Kb... but the actual max (byte) address is 65535. If we were to follow what it appears IBM did, we would have been referring to 65.5 Kb. I agree that it is annoying that it isn't consistent. Heck - my home PC has 128 Mb... which shows up through the POST as 130nnn (I forget the last three digits).
