[OSy] Msim.conf s 257MB a vice pameti

[Martin Liška]

Hezky den,
   hezke rozdeleni ;) Takze obecne se da rict, ze by mel clovek tedy projit
celou pamet, obejit mista, kde jsou nejaka zarizeni a utvorit si list
intervalu pameti, kam se uspesne zapisuji data (test, zda je pamet moje) a
to prohlasit jako pamet k dispozici?

Diky,
ML
