..even tough it won't work anyway, because command.com relies on the DOS-Kernel, it's just a command interpreter. I already explained it here: http://www.wimsbios.com/phpBB2/viewtopi ... 4&start=15

Ok, as you're using a "DOS-based" OS, this should be possible too (basically you are doing a format a: /s via GUI). Verify that afterwards there is a io.sys, a msdos.sys and a command.com file on your disk (the first 2 are hidden files). If booting still fails using that same bootdisk, there may be ...

As it says: "Insert system disk", you don't need my utility, as it'S already trying to execute the boot sector. My utility is just for Bootblock-versions which request to insert a disk with awdflash.exe so that you are able to boot normally. Are you sure, you created a correct bootdisk with a sane b...

I'm sorry, you must have tried to download the file while my Apache didn't work. I did a apt-get upgrade on my debian box and it failed to restart Apache properly. I came back after a hour and fixed the problem, I'm sorry for the downtime :)

I am curious if stripping the first 64k of the .exe flasher works or not. I got the idea because when i analyzed the file, i found some padding bytes in there and i found out from the .exe, that the bios seems to be 512k in size. Everything in the .exe that can be considered program code was within ...

OK, i downloaded one of these .exe files and recognised, that there seems to be a 512 K flash ROM. I analysed the header of these flash .exe Files and the bios flash-routine seems to be 1 segment (64k) and the rest of 512k is the BIOS .bin file, I think. So you just have to strip the first 64k of th...

It's not that simple.. When you rename command.com to .exe, the file format still remains .com, meaning, that there is NO .exe Header in it. Now if the bootblock expects a MZ - header, it searches for an EIP in the .exe file in order to know to which location it has to jump to start executing the Ex...

Ritchie: Are you sure, that copying command.com to awdflash.exe worked? As a .com file is a one-(64k)Segment (originally CPM-Style) program, which doesn't has its own data, code and stack segments like we know from the MZ-Format EXE-files, I don't think that the boot-block would like to execute it, ...

MASM

Well, I already compiled it, just download the package mentioned above. I also tried to compile it with my old MASM first, but with MASM, my program only outputted garbage, so I rewrote it for TASM. Hint: I found the following site in google, where you can download TASM, if you're interested: http:/...

.EXE

Well, it promptf you for awdflash.EXE, so it obviously is able to read and execute the MZ file format, and I think, it expects MZ. So renaming from .COM wouldn't do it.
But if you have a chance, you may give it a try.

Solved..

Once again, I seemed to have solved the problem myself. I wrote a little loader, which executes the code in the boot-sector of a Floppy, so that I'm able to load MS-DOS, even when only the boot block BIOS works. It provides us Keyboard, Disk and Disply Interrupts, so that we still can use ms-dos nor...
