Here is some info I found for you
DMI or DesktopManagement Interface is a layer of abstraction between system
components and the software that manages them. The System Management BIOS (SMBIOS) is an
extension of the Basic Input Output System (BIOS) that formulates and delivers this
information to the operating system. The pool data is the information. In short, when the
BIOS is "Verifying DMI pool data" it is verifying the table of data it sends to the
operating system (Windows, etc.). If it isn't sucessful, it should return an error.
Wait a reasonable period of time for it to finish. It may make take some time or it may be
stuck. Possible fixes:
1. If you changed the hardware just before this problem occurred
(e.g., installed a new hard disk drive), unchange it.
2. If you installed a new hard disk drive, set the motherboard CMOS Setup to Auto for the
drive type. You may have to disconnect the drive first.
3. Enable "Reset Configuration Data" (may be "Force Update ESCD" in some CMOS Setuups) in
the motherboard CMOS Setup PNP/PCI configuration. (Rebooting will automatically disabled
it after it has done its thing.)
4. The CMOS may be corrupted. Clear it.
