8 <H2>Older SCO Unix versions</H2>
10 NTP 4.0.x does not run on SCO Unix prior to version 3.2.5.0.0. If you
11 need NTP on an older SCO Unix system and don't mind to modify your
12 kernel, use 3.5.91 which has patches for SCO Unix 3.2.4.x. Apply the
13 kernel modifications as described in
14 <A HREF="http://www.echelon.nl/en/ntp/sco3-recipe.html">XNTP on SCO
17 <H2>Compiling NTP</H2>
19 Delete the old SCO supplied NTP programs using the "custom"
20 utility. Run the NTP configure program with CFLAGS="-b elf -K
21 <I>processor-type</I>" for best results.
25 Run "tickadj -As" after every reboot to set the variables
26 "clock_drift" and "track_rtc" to the right values.
28 Run "ntpd" with a high negative nice-value, i.e.
29 "nice --19 ntpd" for best results.

33 More information on the way SCO Unix and NTP interact can be found in
