Legacy weirdness

It makes me chuckle when I notice some of the weird information my computer gives me as a holdover from the old days. Some people probably don’t remember the days of ‘lower memory’ and ‘upper memory’. Here’s a little reminder about it, in case you need it.

There was a time when a BIOS boot-up report of available lower and upper memory was useful, back when the numbers were like “640k lower, 384k upper” and it was likely someone was running MS-DOS with a memory manager. But my laptop’s BIOS still reports it, in the days of Linux and Windows, when the numbers are “640k lower, 2096512k upper”.
