Uz jsem ho pouzil. :-)
Zkusil jsem zatim memtest. Nemam s tim zkusenosti, tak jsem zkusil
zadat "memtest 50" (prvni co se mu alokovat).
A asi to vypada, ze v pameti jsou nekde vypalene bity.
Test jsem zatim nenechal probehnout az do konce, ale ono to asi mozna
uz nebude ani potreba, jestli se se svou uvahou o vypalenych bitech nepletu. :-(

Mohl by mi nekdo poradit, co se da vycist z toho kusu testu, ktery jsem
provedl?
