wierd things of Xenix 386, help!

[Lieh-Wen Shih]

Can anybody out there help with wierd problem about Xenix: after I
built GNU make, did some 'doscp' and 'dosdir', my system became very
wierd (at least to me!) as follows:

	'ps' got a msg of "/dev/kmem can't open",
	'df' got "/dev/root can't open",
	'mkdir' got "can't create directory xxx", and
	'rmdir' got "xxx not removed".

Does anyone know what went wrong? and how to fix?  Any help is appreciated.
