Здравствуйте!

Объясните, пожалуйста, куда может потеряться память:

в dmesg:

Warning only 4GB will be used.
Use a PAE enabled kernel.
3200MB HIGHMEM available.
896MB LOWMEM available.

Т.е. 4Г вроде присутствует (warning, правда, непонятен), но /proc/meminfo 
(а за ним top и т.д.) говорит другое:

Т.е. куда-то почти 1Г делся. На округление не очень похоже...
По объёму похоже, что в списках не значится LOWMEM: 896M, почему?

Для примера взял старенькую машинку с 1Г, так там вроде такого не видно:

Буду очень признателен за разъяснения!
