Dell 2650, CentOS, and more than 4G of RAM

For those of you who might be running into the same problem I was with using CentOS’s PAE kernel to support more than 4G of RAM – where the system would crash during the boot process – the solution is to upgrade the firmware for the RAID controller. You can find firmware for the PERC (Dell’s rebranded Adaptec RAID controller) on Dell’s web site – it requires two floppy disks and is a self-extracting archive that will write itself to the floppies. Those of you like me who haven’t been keeping floppy drives in your computers will be happy to know that a external USB floppy drive works just fine for writing the firmware.

    Hello. This is likely a shot in the dark, but I’m wondering if I could ask you about an account you seemed to have made on livejournal a long time ago:

    I’d just like to ask if you’ve abandoned it or not. I’m very sorry for bothering you, but I figured it wouldn’t hurt to ask and I wasn’t sure where else to contact you.

    Thank you for taking the time to read this! Looking forward to response.

    Hey there, I stumbled upon your page while looking for a fix. I’ve been trying all weekend to get my 2650 to run CentOS 5.2 wiht 8Gb of Ram. Fresh installations fail on first boot. Any idea what Perc firmware you used?
