Hello I am new to FreeDOS and would like to ask for any helpful hint how to create an modified ISO image from the actual FreeDOS version 1.2. My "aim" is simple - based on the FD12LGCY.iso image to create a bootable DOS ISO image with BIOS firmware upgrade software (DOS based). I found several how-tos on the web, but they are all based on the old FDOEMCD or FDOEMCD.builder.zip by using isolinux. In the end I was able to create with mkisofs (on MacOSX from homebrew) some bootable ISO image, but it was not helpful, as I could not access on the prompt my included BIOS firmware upgrade software. Instead of using the standard isolinux boot image, I referenced also the boot.img from the FD12LGCY.iso and was able to have the DOS prompt, but again I could not access my included BIOS firmware software, which should be included as far as I understand in boot.img. Unfortunately the boot.img from FD12LGCY.iso is read-only and from FD12LITE.zip has not space left. So my question is: - How can I build a boot.img from FD12LGCY.iso or from FD12LITE.zip that includes my BIOS firmware software? - And how ca I build with mkisofs from a folder including all "requisites" from the actual FreeDOS version 1.2 (without the installer packages) a boot able ISO image (analogous to FD12LGCY.iso) without using isolinux? I would appreciate any hint. best regards. |
