Awdflash.exe的各種參數(shù)使用說明:
/?:顯示幫助信息
/py:自動(dòng)完成BIOS的刷新任務(wù)
/sy:備份原來的BIOS到磁盤
/sb:在升級(jí)BIOS時(shí)強(qiáng)行跳過BootBlock模塊
/cp:在刷新結(jié)束后清除即插即用數(shù)據(jù)(ESCD)
/cd:在刷新BIOS結(jié)束后清除DMI數(shù)據(jù)
/r:在刷新BIOS結(jié)束后自動(dòng)重啟動(dòng)
/pn:不運(yùn)行升級(jí)程序
/sn:不備份系統(tǒng)老的BIOS文件
/sd:保存DMI數(shù)據(jù)到一個(gè)文件
/cks:在更新BIOS時(shí)顯示備份文件的數(shù)據(jù)
/tiny:只占用很少的內(nèi)存
/e:刷新結(jié)束后自動(dòng)回到DOS命令行狀態(tài)
/f:刷新時(shí)使用原來的BIOS數(shù)據(jù)
/ld:在刷新結(jié)束后清除CMOS數(shù)據(jù)并且不重新引導(dǎo)系統(tǒng)
/cksxxxx:將老的備份BIOS文件與新的BIOS文件進(jìn)行比較校驗(yàn)
想要自動(dòng)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(diǎn)了
================
有軟驅(qū)嗎?
可以制作BIOS刷新軟盤~
首先,如果你的系統(tǒng)處于超頻狀態(tài),請(qǐng)先恢復(fù)正常,然后關(guān)閉BIOS設(shè)置中所有有關(guān)電源管理的項(xiàng)目,并關(guān)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(jīng)格式化的軟盤,用“SYS ? C ? A”命令將系統(tǒng)文件復(fù)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(shè)為newbios.bin)一起復(fù)制到A盤,最后在軟盤上創(chuàng)建一個(gè)批處理文件autoexec.bat,內(nèi)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(xiàn)在軟盤上已經(jīng)有了以下文件:Awardfalsh.exe、newbios.bin、autoexec.bat、msdos.sys、io.sys和command.com。用軟盤啟動(dòng)計(jì)算機(jī)后,計(jì)算機(jī)將自動(dòng)刷新BIOS了,如果刷新失敗也可以用這張軟盤來恢復(fù)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(qū)中取出,并進(jìn)入BIOS設(shè)置從新調(diào)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(fù)。 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(jìn)去恢復(fù)。。。
一般PC/筆記本 BIOS 不會(huì)有socket的,節(jié)約成本, 我估計(jì)只有用焊槍了。 把維護(hù)手冊(cè)給你,上面又怎么拆下來CMOS電池,同時(shí)也有如何修復(fù)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(shè)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!
