Replaced one of the 1066 MHz DDR3 SDRAM cards with a 2 GB or GiB card. # hwinfo --memory 01: None 00.0: 10102 Main Memory [Created at memory.74] Unique ID: rdCR.CxwsZF jVASF Hardware Class: memory Model: "Main Memory" Memory Range: 0x00000000-0xa9c90fff (rw) Memory Size: 2 GB + 768 MB Config Status: cfg=new, avail=yes, need=no, active=unknown Set up the HDD with GPT.
