What is the BIOS?
BIOS stands for Basic Input Output System. The BIOS ensures that your computer and its hardware can be started. The BIOS contains a type of software that enables the computer to use a hardware specific routine check and run. The BIOS contains the instructions that include looking at your memory, processor, hard drive, your CD-ROM devices, keyboard, etc. The BIOS is so large a list of devices. If your computer has booted the operating system looks, this is Windows, Mac OS or Linux, to your BIOS. Through the BIOS happens to control the hardware. This user does not see you as. If your BIOS is too old so he will not recognize new hardware so you get problems and possibly hardware not working properly. Also errors in the management of your hardware can cause problems. An outdated BIOS creates all sorts of problems, including the overheating of the motherboard by a low speed of the cooler running. These bugs are to upgrade the BIOS solved.
The computer now flashing on an Acer Aspire 7720Z. The manufacturer makes no warranty on a machine running Linux. The flash programs are mostly driven DOS on a Linux machine, making it virtually impossible to upgrade your BIOS. Fortunately, for such matters solutions.
* A bootable DOS image;
* The BIOS flash files from Acer;
* A blank CD.
The CD burning
* For a Compact Disk we start K3b to burn. K3b is a program where bootable (bootable) CD's can be burned. Choose a new data CD project. To create a bootable CD, we need a DOS-image. * This can be downloaded here.
* The downloaded file is an archive. ** Use a program like WinRAR to extract this archive. The extracted file is called Dos-Bootimage.IMA.
* Go back to K3b and go to Project â†’ Edit boot images. Click New and choose the DosBootimage.IMA. You should now appear in the boot images. Click OK.
We are looking for the BIOS flash files from Acer. This can be found at the site by the supplier of your motherboard to look for the latest BIOS version. The site contains the Acer BIOS version needed for the Acer Aspire 7720Z. Download the correct file and open it. This makes use of version 1.40. In some newer BIOS can vary the numbers. The name of the file can be adjusted. In this case, you see 4 things are:
Unpack the file without WinFlash (the WinFlash the Vista tool) in the name. Here is CL50140A.zip. Open this file, this file is a directory. Unzip into a folder. The following files appear:
Go back to K3b and add 4 files to the CD project. Burn the CD.
The flash process
Restart the computer and set your BIOS so that boot from CD. Reboot again. The CD starts of the CD in DOS mode. For people with Qwerty keyboard, the CD is in QWERTY mode so you will have to find the correct letters briefly, already a little help 'M' is the ':'. The files you've burned on the CD are available from the cdrom drive if you browse to it first. In this case it was the d: drive. So, type drive letter with a colon after. If so D: and enter.
Now type "dir", you see the flash files appear:
Now type 'if50.bat':
The program starts to flash and immediately starts to flash. Wait until the computer is finished with this and wait until the computer turns itself off (turn on the computer itself when you're told that the flash procedure is completed). Restart your computer and get the CD out. If it is good then your bios is now upgraded. If it went wrong you should look for a BIOS recovery disk and procedure.
