If you dual boot with W98 and your computer Blue Screens with any of the following messages:

<b>   HAL: MP_PTR invalid checksum

   HAL: MPS MP structure not found HAL: No MPS Table Found

   HAL: This HAL.DLL requires an MPS version 1.1 system Replace HAL.DLL
   with the correct hal for this system The system is halting</b>
when shutting down W98 and selecting Windows NT, but doing a cold boot works, then your BIOS is old and requires replacement.
