PFKT44A/PFJT44A:
      Update patch file for processor 0683S2

      This BIOS update addresses Intel Errata G85 and E76.  This Errata 
         effects 933 MHZ / 1GHZ 'B' Stepping Level Pentium III processors, only. 
         (i.e. A and C Stepping Levels are okay, as well as B levels at speeds 
         lower than 933MHZ.)

      This BIOS includes a patch from Intel which Intel believes prevents a
         potential data error problem.  Although Intel states that the problem
         can only occur under certain limited temperature and voltage conditions, 
         IBM strongly recommends updating your BIOS immediately.

      For those customers who wish to use the new processor patch code 
         without updating their current level of BIOS, please refer to the
         "README.1ST" file.

PFKT45A/PFJT45A:
      Set "32-Clock Retry Enable" bit on in the ICH.
      Do not send a character to serial port while detecting the presents of a
         device.

PFKT46A/PFJT46A:
      Fix for manufacturing, no memory error.
      
PFKT47A/PFJT47A:
      Updated Adaptec SCSI BIOS.
      
      Because the SCSI BIOS is updated, expect the following messages to display.
      
      During the first boot after flashing the system bios, expect these messages
         AIC-7899A  .......   - SEEPROM checksum error has been corrected
         AIC-7899B  .......   - SEEPROM checksum error has been corrected
               Press any key to reboot
               
      During the second boot, expect this message
         AIC-7899A    A mismatched single image master configuration has been detected
         (the SCSI devices are listed)

PFKT48A/PFJT48A:
      Fixed booting with 4 GB of RAM and ServeRAID adapter installed.
