Should I give this tutorial a shot?

[Moozillaaa]

sudo cp ~/NewBiosFiles/* /tmp/cdr


What goes in place of NewBiosFiles ?

My extracted file contained a folder in which there are 3 files - ROM file, batch file, and application file...

Is it 'TitleOfFolder'??? In my case, Motherboard_AMD_SocketAM2_A7DA_BIOS_81BF1PO9 ???

[ciscosurfer]

[...] Should I give this tutorial a shot?

If you can, I would suggest using a native Linux updater if Lenovo provides one. Otherwise, make sure you read and understand what you are getting into before beginning the process.

The later posts in this thread address various ways of utilizing GRUB2 to update your BIOS -- I would suggest this method if you are coming up against size constraints (I've found it to be the easiest way and it's slick). The first page of the thread also has GRUB2 and size constraint links as well as other info worth taking the time to read.

Good luck!

Mentioned on page 1 under method 1 and method 2:

Note: "NewBiosFiles" listed below is pseudocode for the extracted location of the new BIOS image + related files that you just downloaded

[Moozillaaa]

Mentioned on page 1 under method 1 and method 2:

Yes - I saw that.

I presumed that the 'extracted location' was the folder in which the 3 files are.

But no? The 'extracted location' is the entire filepath? OR, is the folder name INCLUDED after 'Desktop'???

Unless you change directories to that folder, then the full absolute path would be required.

If the extracted zip folder resides on your Desktop and Motherboard_AMD_SocketAM2_A7DA_BIOS_81BF1PO9 is the name of this folder, and the three files you mentioned are contained in that folder, then the correct syntax should be

sudo cp ~/Desktop/Motherboard_AMD_SocketAM2_A7DA_BIOS_81BF1PO9/*  /tmp/cdr
#this line above is the same as this line below
sudo cp /home/chuckbhp/Desktop/Motherboard_AMD_SocketAM2_A7DA_BIOS_81BF1PO9/*  /tmp/cdr

If I've misunderstood your question, let me know.

[Moozillaaa]

I still cannot copy these files to the /tmp/dir

[...]What is my incorrect syntax here

Command line tab completion and character escape sequences are beyond the scope of this tutorial. Suffice to say, you either need to escape those backslahes with additional backslashes or use command completion via the tab key to finish out the line. To get around this entirely you can rename the Motherboard\AMD\SocketAM2\A7DA\BIOS\81BF1P09 directory to something easy like biosfiles by right-clicking the directory on your Desktop and choosing Rename.

I re-named the folder to 'Motherboard', and modded filepath, and got to the next step...

sudo cp ~/Desktop/Motherboard/* /tmp/cdr

What will that make THIS

mkisofs -o newBIOS.iso -b FDOEM.144 FDOEM.144
and THIS:
cdrecord -v newBIOS.iso

Motherboard.iso?



And will 'cdrecord' become 'Brasero'?

The options for genisoimage (mkisofs) can be found in its man page

man genisoimage

or

genisoimage -help

The options (or flags) on this line

mkisofs -o newBIOS.iso -b FDOEM.144 FDOEM.144

means:

SYNOPSIS
       genisoimage [options] [-o filename] pathspec [pathspec ...]

-o filename
              Specify  the  output  file for the the ISO9660 filesystem image.
              This can be a disk file, a tape  drive,  or  it  can  correspond
              directly  to the device name of the optical disc writer.  If not
              specified, stdout is used.  Note that the output can also  be  a
              block  device  for  a  regular disk partition, in which case the
              ISO9660 filesystem can be mounted normally to verify that it was
              generated correctly.

-b eltorito_boot_image
              Specifies the path and filename of the boot  image  to  be  used
              when  making  an El Torito bootable CD for x86 PCs. The pathname
              must be relative to the source path  specified  to  genisoimage.
              This  option  is required to make an El Torito bootable CD.  The
              boot image must be exactly 1200 kB, 1440  kB  or  2880  kB,  and
              genisoimage  will use this size when creating the output ISO9660
              filesystem.  The PC BIOS will use the image to emulate a  floppy
              disk,  so the first 512-byte sector should contain PC boot code.
              This will work, for example, if the boot image is  a  LILO-based
              boot floppy.

              If  the  boot image is not an image of a floppy, you need to add
              either -hard-disk-boot or -no-emul-boot.  If the  system  should
              not boot off the emulated disk, use -no-boot.

              If -sort has not been specified, the boot images are sorted with
              low priority (+2) to the beginning of the medium.  If you  don't
              like  this,  you need to specify a sort weight of 0 for the boot
              images.

So this line

mkisofs -o newBIOS.iso -b FDOEM.144 FDOEM.144

means:

Create an El Torito-like bootable ISO9660 image called newBIOS.iso from the FreeDOS image that was modified to include the new BIOS image. Once this line is called, you can use whatever burning program you see fit: k3b, brasero, cdrecord. If you use brasero remember you are wanting to burn an image. The name newBIOS.iso is arbitrary and unrelated to the name of directory that contained your new BIOS image files. You can call it frodo.iso if you want.
