感謝!
確實是775,最近修理的case和樓主狀況一樣,
滿板(asus p5ld2)灰塵,cpu濾波電容爆掉數顆,
剛過三年保固(2008/5購)



清掉灰塵換了電容仍舊無解,才以debug卡來檢驗


以前修理過的板子都會跳碼,唯獨這板子不跳,始終”00”,
查手冊ami bios代碼為
“已將程式碼複製到特定區域,準備將控制權交予int-19開機啟機載入程式(boot loader)

int-19
http://vitaly_filatov.tripod.com/ng/asm/asm_001.12.html
This interrupt is not a substitute for a Ctrl-Alt-
Del warm boot. This interrupt is the last action
performed by the Power-On Self Test (POST), which is
activated by Ctrl-Alt-Del. If a user program
attempts to execute this interrupt directly, the
machine may lock up.

To correctly reboot within an application program,
jump to FFFF:0h in memory. That is, set CS to FFFF
and IP to 0. This is the same process that occurs
when the machine is first powered on. Following
these steps will perform a "cold" boot. To perform a
"warm" boot using this method, first set the word at
location 0:472h to 1234h. This will simulate the
pressing of the Ctrl-Alt-Del.

A cold boot initializes all hardware, tests all
hardware, tests RAM, then calls INT 19h to load the
bootstrap loader. This process is performed when the
computer is turned on or a hardware reset button is
pressed.

A warm boot initializes and tests all hardware but
does not test RAM. It then calls INT 19h to load the
bootstrap loader. This process is performed when
Ctrl-Alt-Del is typed.

The sector read from the diskette will in turn read
in the rest of the operating system. A fixed disk
will read in a Partition Table, which will then read
in the correct operating system.

雖然換一塊二手板子是最簡便的方式,但想自己先嘗試一下,
在這種情況下,還有起死回生的可能性嗎?
