My old Dell Optiplex GX150 Mini-Tower has Dell A11 Bios. The maximum RAM the system will support is 512MB-The system won't boot if more that 512MB is added to the "two" RAM slots (Memory Error....). During a chat with the Dell online community I was told that the computer's hardware won't support more than 512MB of RAM. I did some research on the individual motherboard components and have come to believe that the Dell A11 Bios are limiting the RAM but, I'm not sure. I would like to Flash different Bios that allow for adding more RAM and give me greater control over the CPU. Coreboot does not list my motherboard but does list the individual chips except for my specific Northbridge which is an Intel 815 chipset. My board "SCI28-R13" contains: "northbridge" Intel 82815, "Southbridge" Intel 82801 BA/BAM, "Super I/O" NSC PC87364, and the "CPU" is an Intel Pentium III 686. Will coreboot work with my computer? Will I be able to add more RAM if I flash coreboot? And if so, can someone hold my hand and walk me through the process so I don't turn my Dell into a boat anchor?
