BIOS Boot-CD

Howto: BIOS-Update per bootable CD


BIOS Update per bootable CD under DOS

A guidance how to create a Boot-CD (which contains the Freeware version of Caldera DR-DOS v7.03) to perform a BIOS update.

see also: BIOS Update per bootable USB-Stick
see also: BIOS Update per DOS-Boot-Diskette

 

Important: this method simulates/emulates a floppy drive. Due to the size limitation of a 2.88MB floppy disk, you can only use a BIOS file and flashtool whose total file size is max ~2.7MB!

Recommendation: i prefer to use the method BIOS Update per bootable USB-Stick!
A bootable pendrive has no size restrictions and more importantly: you can create a BACKUP before updating the BIOS - and that's always a good idea!

 

The following tools are needed:

  • CDBurnerXP - free CD-Burning software, Download from manufacturer's website
    Attention: download the CDBurnerXP-Version without OpenCandy! (OpenCandy = Adware!)
  • UltraISO - Trial version, Download from manufacturer's website
  • Ultimate BIOS-Boot-Edition:
    - drdos.img (the boot image file contains the 3 DR-DOS system files command.com, ibmbio.com und ibmdos.com)
    download [1] Ultimate BIOS-Boot-Edition - 5.9MB

 

Instruction to create a bootable CD

  • Tip: use - if possible - a rewritable CD-RW.
  • Open the Ultimate BIOS-Boot-Edition and extract the boot image file (folder boot_cd) drdos.img.
  • Install and start the Trial version of UltraISO.
  • Open the boot image file drdos.img with UltraISO.
  • Rename the filename of your flashtool and the BIOS file, if they have more than 8 characters (not the file extension!).
  • Copy the flashtool and BIOS file (with Drag&Drop) to the other existing files (see picture).
  • Save the boot image file and close UltraISO.
  • Start CDBurnerXP and choose Data disc:
  • In the CDBurnerXP main menu Disc choose the entry Boot options...
  • In the following window (see picture) enable the checkbox Make disc bootable and insert the path to your boot image file drdos.img.
  • Change the Emulation type to Floppy 2.88MB.
  • Click the OK-Button to close this window.
  • Now you can use Ctrl+B to burn the CD.
The DOS system files are normally invisible, because their file attribute is set to hidden. If you would like to show these hidden files, you have to enable the option: "Windows-Explorer / Tools / Folder options / View / Show hidden files and folders" and to disable the option "Hide protected operating system files".

 

Starting the BIOS-Update from CD-ROM

  • First, go into your BIOS-Setup and change the Bootsequence to CD-ROM (search for an option like Bootsequence, First Boot Device, or something similarly).

  • Insert the CD and restart your PC. If all went well - DR-DOS starts and you can see the famous DOS-Prompt (A:\>).

  • Now you can start the BIOS update, but remember: you can't backup your old BIOS version onto a CD! But if your harddisk has a FAT16- or FAT32 partition, it would be a good idea to copy your 2 BIOS files to this partition, and to start the update/backup from your harddisk.

Happy flashing!

Maybe you have an installed BIOS version which only supports *nix/ubuntu?

When i try booting from CD/DVD ROM it would tell me that it doesn't recognize anything, only recognized ubuntu's discs..

Boot from the W7-CD, delete all Ubuntu partitions, create new partition and format the partition with NTFS. Install W7.

Hi. How can i install windows 7 or any windows cd, after i installed ubuntu and accidentally deleted windows NTFS?... Now my pc is running ubuntu, but i can't really do much because is extremately SLOW.. And when i say Slow, i mean, it would literally take 4 minutes to open Ubuntu Center or any app. Help!

Franklin Castro 19.Feb.2013 08:34

Thanks a lot! This is exactly what I needed to include HD204UI firmware HD204UI_JP.EXE file update into Caldera DR-DOS CD-ROM to update my firmware-faulty 2TB Samsung hard drive to version 1AQ10003 (HD204UI_JP.exe) since my motherboard GIGABYTE - Motherboard - Socket 775 - GA-X38-DS5 couldn't boot using USB memory stick (I tried using both the back and front USB ports). I rename the file to 123.EXE to follow 8.3 file format rule as per DR-DOS operating system. This DR-DOS CD-ROM method is much easier and more straightforward way to update hard drive firmware than using FreeDOS. I am happy since I finally fixed two things: 1) Recover data size of my hard drive to 2TB after firmware fix. 2) Recover 1.1TB of DATA itself after right disk size was adjusted by firmware update (thanks God!). I updated firmware of a second HD204UI and now they live together inside my NAS (Synology DS211J+) without the data loss bug (http://sourceforge.net/apps/trac/smartmontools/wiki/SamsungF4EGBadBlocks) 3) Here in Dublin, Ireland, the minimum charge for a data recovery to do this kind of service is 300 EUROS per disk!
