Neznámé programy – dmidecode

Po tom co se mě několik lidí zeptalo na dotaz, jehož odpověď je název programu, rozhodl jsem se takovým programům věnovat trochu prostoru v blogu.

První na řadě je program dmidecode . Ten zobrazí různé informace o hardware počítače.

Takže třeba pokud nevíte jaké paměťi máte v počítači, stačí se podívat na jeho výpis:

 Handle 0x0008
        DMI type 6, 12 bytes.
        Memory Module Information

A hned je jasné, že máme obsazení dva sloty paměti a jeden zbývá volný. Podobné informace můžeme získat o PCI sběrnici a u novějšího hardware i o integrovaných portech:

Snad se to někomu bude hodit :-).
