This is an older server. I have to boot it from a SmartStart CD to
access the system configuration in it, and I couldn't enable the
advanced mode to see whether or not APIC is enabled. But, after
switching to another OS profile (Linux) there it seems that issue got
fixed. After I did the change, I can see that the CPU has the feature
APIC:

CPU: Intel Pentium III (797.48-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0x683  Stepping = 3
  Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE>

Before that, it did not:

CPU: Intel Pentium III (797.48-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0x683  Stepping = 3
Features=0x383f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE>

PS: Sorry it took some time to check up on this. The server is in a
co-location facility, and I don't go there often.

PS2: On other Compaq/HP servers, I've had success setting APIC mode to
"full table mapped". I just couldn't find that on this one, the system
configuration does not give me any advanced options or mode.
