笔记本BIOS

Awdflash.exe的各種參數使用說明:
/?:顯示幫助信息
/py:自動完成BIOS的刷新任務
/sy:備份原來的BIOS到磁盤
/sb:在升級BIOS時強行跳過BootBlock模塊
/cp:在刷新結束后清除即插即用數據(ESCD)
/cd:在刷新BIOS結束后清除DMI數據
/r:在刷新BIOS結束后自動重啟動
/pn:不運行升級程序
/sn:不備份系統老的BIOS文件
/sd:保存DMI數據到一個文件
/cks:在更新BIOS時顯示備份文件的數據
/tiny:只占用很少的內存
/e:刷新結束后自動回到DOS命令行狀態
/f:刷新時使用原來的BIOS數據
/ld:在刷新結束后清除CMOS數據并且不重新引導系統
/cksxxxx:將老的備份BIOS文件與新的BIOS文件進行比較校驗
想要自動刷新回去再軟盤的autoexec.bat中輸入:
Awdflash.exe ? *.bin ? /sn ? /py
如果不行,就要找維修點了
================
有軟驅嗎?
可以制作BIOS刷新軟盤~
首先,如果你的系統處于超頻狀態,請先恢復正常,然后關閉BIOS設置中所有有關電源管理的項目,并關閉BIOS緩存(“sysetm ? BIOS ? Cacheable”)和顯卡BIOS緩存(“Video ? BIOS ? Cacheable”)。
然后在DOS下插入一張已經格式化的軟盤,用“SYS ? C ? A”命令將系統文件復制到A盤,然后把Awardfalsh工具(一般主板配套光盤里有)和最新的BIOS文件(假設為newbios.bin)一起復制到A盤,最后在軟盤上創建一個批處理文件autoexec.bat,內容如下:
@echo ? off(回車)
if ? exist ? oldbios.bin ? goto ? awdflash.exe ? newbios.bin ? oldbios.bin/py/sy/cc/cp/cd/sb/rgoto(回車)
endawdflash.exe ? oldbios.bin/py/sy/cc/cp/cd/sb/rend
好了,現在軟盤上已經有了以下文件:Awardfalsh.exe、newbios.bin、autoexec.bat、msdos.sys、io.sys和command.com。用軟盤啟動計算機后,計算機將自動刷新BIOS了,如果刷新失敗也可以用這張軟盤來恢復以前的BIOS。
注意:AwardFalsh刷新工具版本必須在V7.70以上,刷新后將軟盤從軟驅中取出,并進入BIOS設置從新調整即可。

BIOS is the basic software of PC. If it is crashed, You could not start the PC.
If you can get the bios chip out(See whether there is a socket in your mother board, usually 32 pins), I can't help you flash it(Use external flash device).
(Believe me. I am a firmware engineer focusing on BIOS development...).
是BIOS,不是CMOS, CMOS可以放電,BIOS壞了只能拆下來才能恢復。 有socket的容易拆。沒有socket的只能用焊槍拆了,然后用外面的flash device burn BIOS binary image 進去恢復。。。
一般PC/筆記本 BIOS 不會有socket的,節約成本, 我估計只有用焊槍了。 把維護手冊給你,上面又怎么拆下來CMOS電池,同時也有如何修復BIOS。注意CMOS電池被拆下以后,BIOS里面的信息將全部丟失。指的是自己設定的信息。
Sorry in Company right now, no Chinese input.
BIOS is stored in NOR flash ROM chip, it don't need battery to keep information. CMOS is
another RAM chip, it need battery to keep configuration information. These data in CMOS are
not important data, once BIOS is running, they can be resumed back to default value. Then
you can re-config them and save them into CMOS.
When PC is power-on, CPU will copy BIOS software from ROM into system memory and run it.
BIOS software will read config data from CMOS to initialize hardware...
LZ Notebook's BIOS software in ROM chip is crashed because of burning error. So it can't
boot notebook.
I just saw the datasheet. Maybe it has a solution.
See page 98.
Repairing the BIOS IC
(Service Partners Only)
The notebook’s BIOS IC cannot be replaced separately. If it is defective, you must replace
the
motherboard. In some cases, however, you might be able to reprogram a malfunctioning BIOS IC
using either e-DiagTools for Windows, a BIOS floppy disk, or a Crisis Recovery floppy disk.
You have to have BIOS floppy disk, or a Crisis Recovery floppy disk. Then press Fn+B to
power-on. Then CPU will read floppy software as BIOS instead of reading BIOS chip.
Unfortunately, if you have no BIOS floppy disk, or a Crisis Recovery floppy disk.
you only have to get the chip out...
Good luck!
