I have been having some problems with FreeDOS
changing drive letters on me unexpectedly so that it is unable to find it's own
command.com
I am ultimately trying to get a system which will dual boot FreeDOS and Windows XPe, so that I can boot into DOS to allow the windows system files to be updated automatically. Initially I downloaded an ODIN floppy disk image and used it to create a bootable CD in floppy disk emulation, using Nero. This booted successfully, and allowed me to partition and format the hard drive. However, when I then booted from the hard drive, although it listed the three partitions correctly during the boot, it complained that COMMAND.COM was missing. Having found a command.com for it to use it became apparent that the C: drive was in fact the 5Gb empty partition and not the small DOS partition which had COMMAND.COM on it. No to be defeated I went back to the web site and downloaded a FreeDos image and used rawrite to create a bootable floppy that I could use in a USB floppy drive. Boots OK, although with very confusing options during the process - eventually wait and choose R to run programs from the command line. Re-format the HD as before, reboot to HD and alll is well - it works! Until I remove the floppy drive and boot from the HD and then the drive letters change again and it can't find command.com. Following some advice from a posting on the
forum I tried following a link to an alternative 'development' kernel - same
nominal version, but this kernel works correctly with or without the floppy disk
being present, and I could add the XCDROM drivers to be able to read CDs as
well.
The moral is that the kernel version sare not
clearly identifiable, but may cause some strange problems with early
version.
Hope this helps someone,
