What does BUFFERS (config.sys) say?
What kernel version (ver /r)? Try again with an older (e.g. 2041) kernel.
Is this atop FAT16 or FAT32?
What host and guest cpus are you using?
How much RAM is available? (Use more than 64 MB.)
Does anyone know what extender (e.g. Causeway) the installer is using?
What VirtualBox version? Is VT-X enabled? (Recent versions only run on
64-bit hosts with VT-X enabled.)
And yes, disable DOSLFN ("doslfn d") first, if it's loaded.
(Sorry, I haven't tried it myself.)
