- plošča se zažene in prikaže prvi ekran
- namesto, da bi nadaljevala z zagonom, se ugasne in čez par sekund ponovno prižge
- ko se ponovno prižge, na ekranu ni več slike, gori lučka za napako pomnilnika (DRAM_LED), diagnostični ekranček kaže status (Q-code) 55, kar po manual-u pomeni "Memory not installed". V tem stanju plošča ostane
Nalagal sem BIOS iz ASUS-ove uradne strani, odveč je tudi govoriti, da se hardver po ugrade-u BIOS-a ni spreminjal. Torej je vzrok v nadgradnji BIOS-a, kljub temu, da nadgradnja (ki je bila zagnana iz samega BIOS-a), ni javila nobene napake.
Na spletu sem našel sotrpina, ki se je s to težavo spopadal že kar en čas nazaj:
sdavm je napisal/-a:So, during my research in trying to get to the bottom of that, someone suggested that I might need to update my BIOS. I checked on the ASUS website and, sure enough, a new version of the BIOS for my mobo was just released in mid February.
I downloaded it, read the instructions and warnings concerning how to install it and decided to again use the ASUS utility designed to update the BIOS for you. The utility said the install was successful and my machine began to reboot. Everything looked like it was going well except that when it got to the BIOS screen, it would fail to boot and then would just restart the machine, doing that over and over a couple of times until the machine just stays on while showing a totally blank, dark screen.
There are two LEDs that light and stay on inside the box while it attempts to boot. One, is the "Boot Device" LED and the other is the "DRAM" LED. Additionally, the error code eventually settles on 55 which, according to the manual, means "memory not installed" (I'll get back to that in a minute).
... in zadevo tudi rešil, ampak ni bil čisto prepričan kako
sdavm je napisal/-a:So, at this point I did several things: First, I went to the ASUS website and downloaded the updated bios and put it on a USB flash drive. Then I disconnected all my other drives and anything else that was connected to my computer that it could conceivably try to boot from so that it had no choice other than to boot from the USB drive. Then I tried to start it with only one stick of memory in the slots. Still, it would not post ... it would just turn on and show a dark, blank, screen. Then, I thought maybe the specific memory stick was bad so I kept substituting different sticks, putting them in different slots. I essentially disconnected and reconnected just about every internal component other than the graphics card, liquid cooling, and fans until, suddenly --much to my amazement --when I had arrived at the combination of having just two of the 4 slots of memory occupied, my machine suddenly noticed that it had a bios update on the USB drive and began loading it. Then, this time, when it rebooted, it gave me the screen that I had been hoping to see, the one that gives you access to go in and make changes to the bios. Once I saw that screen (I was relieved, btw that it was the updated version of the bios that I had loaded onto the USB drive) I went in and selected the option to restore the optimized defaults, restarted it, and it booted right into windows!
Sam sem se igral z:
- menjavo grafične kartice
- menjavo pomnilnika
- poizkusi z boot-anjem z vključenim USB-jem, ki je imel nov BIOS na root-u
- resetom nastavitev pomnilnika z držanjem gumba MemOK
- resetom BIOS-a z odstranitvijo baterije in pritiskom na namenski gumb "Clear CMOS"
Skratka, kar nekaj telovadbe je že za mano. Ostane mi še, da najdem en starejši manjši USB ključek in poizkusim z njim (če slučajno prime). Drugače pa bo potrebno na novo naložit BIOS z nekim zunanjim programatorjem. Tega nisem še nikoli delal, tako da imam par vprašanj:
- iščem predloge za nabavo programatorja, ki bi znal to narediti
- razmišljam pravilno, da bi s programatorjem na BIOS čip moral naložiti .ROM datoteko, ki sem jo dobil na proizvajalčevi spletni strani (ali je v igri še kak drug trik)?
Vem, da se na ebay-u dobijo sprogramirani BIOS čipi za cca. 10 EUR, ampak če ne bo "šola predraga", bi želel zadevo rešiti na težji način
Pa še par slik same problematike:
- Naziv matične plošče.
- Dodatna nalepka
- Slaba slika BIOS čipa
