A guidance how to create a Boot-CD (which contains the Freeware version of Caldera DR-DOS v7.03) to perform a BIOS update.
The following tools are needed:
Instruction to create a bootable CD
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.
@Hara Mo I have the same problem. Were you able to resolve it? Ppalxgr 11.Jan.2015 14:47
Dear, I cannot succeed to burn the cd, it says : 'you did not add any files to the compilation. Do you want to burn the disc anyway? I click yes. Allow making changes to the disc later is selected (but tried also 'prevent further changes to the disc(finalize)'. Clicekd burn disc, then an error occured: most likely the disc is not usable, it's a brand new dvd disc, first tried with two old rewritable cd , same error. error detail: Hresult: 0x80040295Hara Mo 30.Sep.2014 20:03
Thanks you so much! I was struggling to upgrade my Gigabit P55 motherboard bios as i have 64bit windows 7 and no floppy drive. I tired heaps of ways and couldn't get it to work. Your method above (except the burner software) worked like a charm! Thank you for providing a great community service! Maybe think about adding a "Donate" button to donate through paypal as i certainly would!Aaron 24.Sep.2014 01:59

I don't know. Maybe you have made something wrong?
My Acer Aspire 5110 USB ports are unusable. Any USB device connected showing in the device manager as unrecognized, device error 43. I have a slim hope that updating the Bios to the latest version 3.13 will solve the problem. I followed the instructions to make a boot CD/DVD. I copied my bios files to the dos files as shown in your picture and saved it. When I boot up I see the A> prompt as expected. When I list the files on the DVD only see the file "Command.com". If I put another data dsta in the CD rom drive with my Bios files they don't don't show. The disk looks empty. Any thoughts on this..Bill Meyer 15.Oct.2013 15:04

CAN IT WORK ??????vishalshetty104 13.Oct.2013 07:43
Thanks but i found a way to do this. I was actually trying to install my original version of bios cause the newer one wasn't working right. To upgrade its simple, just download which version you want to update it to and click it and run it and follow the instructions. The problem comes when trying to install an older version because it won't let you. So you have to either do something like you said or, you have to find another way around that. I was able to do it using a command in command prompt. It forces the bios version you want to run and install. Anyways thanks, this was still educational.Jay 18.Jun.2013 00:57

Sorry, but most of all stupid Dell PCs don't support a bios flash under DOS. You have to execute the Dell .exe bios update under Windows. Dell also should have a FAQ how to flash your bios.
