Could you share the specific floppy/RAM options for VirtualBox and what
version you are running?
I was able to build the kernel from Linux with OpenWatcom 1.9 and run it in
VirtualBox (v6.1 32MB RAM, 1.44MB floppy, no hard drive) and on my P1-75
(24MB RAM, 1.44 and 1.2MB floppy and 2GB CF).
The defaults there (config.m) were 386+ and FAT32. It looks like it has
the same defaults in config.b.
How are you getting from the built kernel + sys to a bootable image?
I wasn't sure if I could just use the FAT12 bootsector unmodified (sys.c
looks like it does some patching), so I booted into MS-DOS and used the
install.bat from bin to SYS A: and grabbed the built command.com from
ibiblio.
I was unable to successfully complete the build in Windows 7 with either
mingw32-make or build.bat. I'll spend more time poking at this another day.
