RHEL3 no more MTRR available or inconsistent fixed MTRR settings

RHEL3 no more MTRR available or inconsistent fixed MTRR settings

Hello
I have two Proliant DL360 G3

After the boot in /var/log/messages I receive this message

with kernel 2.4.21-9.0.1.ELsmp
mtrr: no more MTRRs available

more /proc/mtrr

Which is the good configuration of the file mtrr not to have these messages more

thank you for your assistance
