I can't necessarily say I have solved this problem. But, I can say it is "fixed" for now on my machine. I have a multi-boot Win7, multi-partition system with SL, Lion and Mt Lion and installer partitions running. Recently, I started to get this "EBIOS Read Error: Error "0x31" on every boot...
First, I reset the mb bios, then turned off/on the legacy usb, fiddled with "auto" and "enabled" etc... all between several boots. The issue continued.
Then I noticed I had a Canon scanner/printer usb plugged in at boot and showing up in the boot setup list. It had been plugged in and "on" when I tested a new installer usb. That is when The EBIOS boot errors all started for me.
I turned "off" the printer, rebooted and the EBIOS boot error went away. Simple as that...
I suspect this has something to do with non-bootable usb devices like data drives, printers, scanners, readers being plugged in and "on" during boot. The exception to this would be a bluetooth, keyboard and mouse usb connections. I cannot say with certainty what causes this problem for everyone. But, I do know that usb flash drives can trigger this issue for me if my printer is "on" at boot. Apparently, this problem appears to have nothing to do with my hackintosh boot configuration. It might be a usb driver issue of some kind.
Thought I'd share. Hope this helps someone out there
