Masalah Flash Bios

Recommended Posts

When a computer is turned on, it goes through what is called a POST (power-on self test) routine. This is a short diagnostic procedure incorporated into the boot sequence by the BIOS manufacture for troubleshooting purposes.

Many times when there is an error in your boot sequence you will receive an on-screen error message. This error was printed by the video card. But, in some cases, the error is detected early in the boot process and the error cannot be received by the video card. The problem may even be caused by the video card or the monitor. This is why the need for beep codes came to be.

ko jadi cam aku gak la....

kalau aku tukar je....

tapi try la tukar jumper bios tu (tengok manual untuk bios recovery...)

tak pun tukar chip bios tu... (ada jual ke?)

aloo..

aku nak tolong pun tak reti jugak..

tp setahu aku, kalu bios out, maknenye mobo ko pun out jugak..

kalu mobo ko support recovery bios, try cari jumper atau ape² yang berkaitan..

try your best..!!!!

p/s: aku paki gigabyte ga 7nnxp, support dual bios..

Try laa buat hot swapping BIOS...

Wokehh cun!!!~

tak batalkan warranti ker... bahaya gak tue, ada risiko utk rosakkan waranti nie

alloo..

hoodlums...bole tak ko terang skit pasal hot swapping bios nie

nak tau gak cam ne nak buat..

board tue aku dah anta rma tp tak de kabaran lg..yg aku tau kalo abit dpt detect yg aku flash bios tade rma...mampus wooo...

aku penah buat kat NF7-S aku..2-3 kali gak kene.so far alhamdulilah berjaya biggrin.gif

hot swap ni cabut chip bios drp mobo time tgh ON

1. cari mobo nf7-s rev 2 yg OK

2. praktis cabut chip bios kat mobo ko.bile dah tahu skill die baru blh buat

3. sediakan 1 disket yg ade bios file yg betul

4. ON mobo yg OK tadi.

5. tekan alt-f2 time mule2 kuar display

6. bile die mintak disket ker ape tu

7. cabut bios asal yg ok tadi (pc tgh ON)

8. masuk chip yg problem.pastikan arah masuk tu betul

9. mule la reflash balik bios yg problem

10. restarr + load default+ save OFF pc

11. cube la bios tu.sure jadi nya

**

- kalau blh casing tu biar berdiri. mobo secara menegak.sbb takut nanti chip tu

terjatuh dan kene mane2 part.

- belatih betul2 cara nak cabut+masuk bios

- pastikan arah yg betul

- DO at u'r own risk tongue.gif

aku rasa sapa2 yg first time buat benda2 nie bacala arahan dulu... ikut satu2, sblm flash ambik note setiap benda penting... insyaallah selamat punya

aku cadangkan kalo kt sesaper yg takleh RMA nf7s-2 yg salah flash bios tuh kasik jer mobo tuh kt sesaper yg bleh buat cam sarge.. pastuh bayar la sket.. kalo ahli kelab AMD tuh, leh la dapatkan technical support.. tongue.gif

arituh puas aku carik saper yg bleh buat.. lupa la plak nak tanya kt sarge.. laugh.gif

takata takleh buat ker??die kat puchong jer unsure.gif

aku jauh laa.nak keno pos lagi.sanggup takpe biggrin.gif

bole mendatangkan faedah kat ahli nie, bagus gak idea nie...

nanti bolela kita letakkan sbg khidmat teknikal utk kelab AMD

arituh aku tanya, dia tanak.. tak tau ler samada tak berani atau pun malas nak buat.. malas kot.. tongue.gif ala.. bukannyer suruh buat free pun, bayar ler sket.. laugh.gif tp takper la, arituh aku tanya sbb aku nak angkat mobo tuh tp yg dah tersalah flash bios punya dr forumer LYN, abistuh dia offer mobo dia kt aku, trus tak jadik.. dah ler offer murah² plak tuh.. blink.gif juling jap aku.. hEhEhEhE

thanx bro takata..

takata tu bisness man.so bizi skit la.takpun tak berani tanggung risiko.aku pun tak berani.nanti ape2 korang salah kan aku.sendiri punye takpe laa tongue.gif

fuhh...

tenqiu kengkawan...byk ilmu nie

tak sangka aku warga putera nie dasyat2.. tongue.gif

kalo tak dpt rma sure aku akan cuba nie...

p/s

sarge ko dok kat mane aaa???

aku nak tanya sikit. Kat mana nak cari bios cip tu? Aku ada 3 mobo yang dah kong

dia punya bios. Aku rasa kalau tukar dia punya bios boleh idup balik Mobo tu.

kat mane nak cari??/susah skit la.yg senang cari mobo yg sama.pastu gune BIOS chip tu utk hot swap

cara-cara buat hot swap ader kat majalah CHIP..

sori aku lupa edition bila punya

selalu aku nak baca CHIP aku g library jeq

save...

hehe

kat dalam majalah tu siap ader gambar
