Some MB support multiple platforms. The 1X00 and 2X00 and 2000 & 4000 models. The change is made by setting the BIOS and Platformbytes at the factory then loading the correct OS. But there can be different memory configurations.
There is a bios flag that is not set correctly. Be careful with this, you can and will render your snap dead
. I know how to correct the problem if it becomes a door stop with the 1 x 2 led pattern. Took me over a year to find a fix. So I'm not giving it out, and advise users not to change the settings.
What needs to be change is the bios flag and/or platformbytes. If you booted from your original HD and the OS did not change (can not tell if the OS version were the same except by watching the led during the first boot), the BIOS flag is set to 0 and needs to be 1. Platformbytes changed according to MB revisions, this needs to be known some over lap models. The problems show up when the snap reboots. Even though the info is not correct it is still working.
This info is displayed by the following commands from debug.
bios model
bios platformbytes
I RECOMMEND NOT MAKING THE CHANGES.
Even though it may effect how the snap behaves.
bios unlock
bios model (this will give current model 0)
bios model 1 (changes to single drive)
bios lock
Please Note that the Snap uses different code depending on model/platformbytes, even though there is only one sup file. If you decide to make the changes, print out and save current values. I will need the values to make the repair.
