Correction 17. MS-5128 & LGS Memory. 9/24/96

MODEL M/B Version Correction Items Solution
MS-5128 1.0 Lucky Gold Star MemoryWhen using memory
made by LG Semicon, computer system cannot
pass Himem.sys when booting up from DOS; cannot pass Winstone 96; hang up and give out some memory error message
under Windows 3.1 and Windows 95, or no screen when boot up. This happen very often on EDO 4x32 60ns 16MB.
The memory chips have the following make:
LGS
GM71C17403BJ69616
KOREA		 Ref.  Alert #009 9/3/96
         Correction #16, 9/16/96

We have released an AMI BIOS version AH75 to solve this problem.
Another solution is to change DRAM RAS to CAS Delay to 3 CPUCLK.

We have released an Award BIOS version WH76 to solve this problem.
If you still experience the problem, please disable Auto Cinfiguration function in Chipset feature setup, and change R/W Leadoff time to 7/6.
