Instruction to create a bootable CD
Starting the BIOS-Update from CD-ROM

Today, there are many PCs and Laptops without any Floppy drive, but many users need to update their Hardware too. For this case we have wrote this short HowTo.

This example works best with Ahead's Nero (v6.0), because it supports creating bootable CDs. But you can use any other CD-Burning software, which supports creating bootable CDs too.

First, you need the Image file drdos.img, which contains a bootable DOS-Diskette. Our choice was the Freeware version from Caldera DR-DOS v7.03. Nowadays devicelogics, but commercial!

Download

drdose.zip 228KB (Size decompressed = 1.474.560 Bytes)
contains the compressed File drdos.img, which must be decompressed with a Packer program like Winzip or Winrar before inserting on CD!

The Image contains only the neccessary DOS systemfiles and different ATAPI- and SCSI- CDROM-Driver. It contains no emm386 or himem, which could compromise the BIOS-Update.

Notice: You can create your own DOS-Image too. All you need is a DOS-Bootdiskette and e.g. the program rawrite from John Newbigin, to build the Image.

Instruction to create a bootable CD

Start Nero, choose (1.) New Compilation and the CD-Format (2.) CD-ROM (Boot).

Open the Menu option (3.) Boot and insert the path (4.) to the Image file drdos.img (example C:\drdos.img).

Next click (5.) the New-Button.

Inside the new window, use the (6.) File Browser to find your Flash program and BIOS Updatefile, and insert these 2 files per Drag&Drop into the (7.) left window.

Click on the (8.) Burn-Icon and toast your CD(-RW).

Starting the BIOS-Update from CD-ROM

First, go into your BIOS-Setup and change the Bootsequence to CD-ROM, otherwise we can't boot from it (search for an menu entry like Bootsequence, First Boot Device, or something similarly).

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

ATTENTION: Drive A: contains the Caldera-DOS and Drive Z: your Flashprogram and the BIOS-Updatefile!

Now, change the Drive from A: to Z:. (insert Z: on the DOS-Prompt and press Return).

Call your Flashprogram and start the Update, but remember: you can't backup your old BIOS Update onto CD! If your Harddisk has one FAT16- or FAT32-Partition, it would be a good idea to copy your 2 Updatefiles to this Partition and start the Update/Backup from there.

Happy flashing!
