- Funny you should say that. Look:
-
- + === grog onlyyou:~ 66 -> ls -l /stand
- + total 7096
- + -r--r--r-- 1 root root 3980 Dec 20 14:56 mip
- + -r--r--r-- 1 root root 4204 Dec 20 14:56 sip
- + -rwxr--r-- 1 root root 1945520 Dec 20 17:40 unix
- + -rwxr--r-- 1 root root 1678764 Dec 20 16:14 unix.old

- The thing is, of course, that I didn't know that, and - like Fred Fish
- - didn't know how to get out of the graphics screen. If this had been
- documented, it wouldn't have been a problem, but documentation is
- almost non-existent.

- BTW, the old kernel is the vanilla flavour, the other one adds TCP/IP
- and NFS support. Compare with a similar kernel under BSD/386:
-
- + === root allegro:/ 503 # ls -l
- + -rwxr-xr-x 1 grog 525857 Dec 17 13:51 bsd
- + -rwxr-xr-x 1 root 498637 Apr 3 1992 bsd.generic
- + -rwxr-xr-x 1 grog 525909 Nov 26 13:25 bsd.old
- + lrwxrwxrwx 1 root 3 Oct 19 16:52 vmunix -> bsd
- + === root allegro:/ 504 #
