Read verify and post UC6 = 16MB UC5 = 8MB

Hi,

*** for those who are stuck on the same device with same chipsets ***

I removed UC5 (8Mb) chip and replace it with 32Mb then I removed the UC6 (16Mb) Chip complately and left the chipset area empty then program the 32Mb chip with bios dump file and BINGO !!! its worked fine

A Bios Program was split into two chipsets But I make it in one chip


Thanks all

Thanks for your information
is there any solution for this type of motherboard

Your laptop configuration is Non vPro ,so it doesn`t have a 32MB chip. You have 8MB and 16MB .

This motherboard indeed contains four EEPROM chips with the following specifications: two 1MB chips, one 16MB chip, and one 8MB chip. The 16MB EEPROM(UC5), which you mentioned is located on the back of the board, is positioned alongside the chipset.

UT6 = 1MB
UT2 = 1MB
UC6 = 16MB
UC5 = 8MB

There is not any EEPROM with 32MB capacity !!!
it make me confuse !
