TITLE:  Manhattan P/V Windows NT 2.50/3.51 Hang
 
 
ISSUE 
 
   The Manhattan P/V Windows NT v3.50/3.51 Setup Disk 1 hangs during 
   install, when attempting to detect installed hardware using 
   NTDETECT (dual processors only).
   
   This issue affects dual processor Manhattan P and V systems ONLY.    

 
BACKGROUND 
 
   This problem is caused by a coupling of erratas on both the 
   Neptune EISA System Component (ESC) IC on the systemboard, and 
   the Pentium CPUs on the processor board, in conjunction with BIOS 
   v1.10.    

 
ACTION 
 
   Update the Manhattan P/V system BIOS to v1.14 (part number 
   905547-312) or higher. File 05547312.EXE is available from one of 
   AST's On-Line! sevices as follows:

   the processor board in your system is at the correct revision 
   level to support dual processors.
