   Folks, I've dabbled in a number of arcane devices over the decades.   
   Sifting through IBM Technoslovakian -AND- poorly written ad copy   
   sharpens one's perception [or destroys it...].   
      
   Mylex discriminates between one CHIP and two CHIP DAC960. Why isn't that   
   SOCKET? Further, one can see two socket DAC960 with one EEPROM.   
      
   So, while Peter has come up with a Baron Von Münchhausen class of   
   fantastical story, it seems quite possumble...   
      
   Some other oorts to run down...

   The only -probably working but yet untested- method to get the old   
   single-flash 960P to a BIOS 3.x seem to include externally copying of   
   the 28F1001 chips. You need two chips, erase them, then copy the   
   firmware with an Eprommer into the lower / upper 128K. Each chip is 128K   
   x 8 bit. The one actually present on the 960P is only the lower. The   
   socket for the upper memory range is yet unpopulated.   
      
   I'd tried stuffing in an empty 128K chip into that socket and then flash   
   to 3.x but the only thing I got was a Raid-Adapter firmware error with   
   the second chip installed right after power on and the "Flasher"   
   software refused to run the upgrade.   
      
   Too bad.
