im desperating to safe my compaq presario cq20-320tu BIOS. Blank display, just the dvd rom LED keep blinking(looks like asking for dvd disc but if i put any dvd in it nothing happen). No beep sound, just lousy dvd rom. I had tried contacting HP support already but they give none information. The method i tried as below : 1. I format a usb flash disk with FAT, also tried with FAT32 too. 2. download sp45717.exe, extract and copy rom.bin to usb flash disk. I also tried with older version of bios. 3. press windows button + B 4. Plug in the power. 5. Now the caps lock led blinking also it read from the usb flash disk, but no sound just silent. I waited for hours and tried many times but that was as far as i could go. It'll result the same if i burn the "bin" files into dvd. Not yet tried with floppy since i don't have one. I also tried renaming bin files with 68phu.bin. I wonder if it searched the correct file name too, since the usb flash disk not blinking for long as like copying 1MB file to BIOS ROM. Once along time ago, on a successful updated bios, i ever backed up the bios to usb flash disk when it requested, and the file name looked like in Hexadesimal. But unlucky i didn't keep this file. I flashed my bios without any backup this time. It said success updating bios and ask for restart. So i restarted and got this disaster. I've ever seen bios of HP elitebook 6930p, and its bios appearance is the same like mine. So i wonder anyone with the same type of my notebook or HP elitebook 6930p got his/her backup file when updating bios. Please tell me, if you have the file or at least the file name. thank you.
