Hi!
I have compaq proliant 6500 with 2xPIII-500 cpu. When I tried to
enable SMP (by uncommenting SMP and APIC_IO), I got this:

Timecounter "i8254"  frequency 1193182 Hz
CPU: Pentium III (686-class CPU)
  Origin = "GenuineIntel"  Id = 0x673  Stepping = 3
  Features=0x383f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,<b25>>
real memory  = 16777216 (16384K bytes)
avail memory = 13701120 (13380K bytes)
Programming 35 pins in IOAPIC #0
IOAPIC #0 intpint 25 -> irq -1
IOAPIC #0 intpint 26 -> irq 0
IOAPIC #0 intpint 27 -> irq -1
IOAPIC #0 intpint 28 -> irq -1
IOAPIC #0 intpint 29 -> irq -1
IOAPIC #0 intpint 30 -> irq -1
IOAPIC #0 intpint 31 -> irq -1

And system does nothing after it.
Then I uncommented:
options     NCPU=2          # number of CPUs
options     NAPIC=1         # number of IO APICs
options     NINTR=24        # number of INTs 
I got error like this:

BIOS basemem (638K) != RTC basemem (640K), setting to BIOS value
found 43 intrs, increase NINTR
panic: you must reconfigure your kernel
mp_lock = 00000001; cpuid = 0; lapic.id = 00000000
Automatic reboot in 15 seconds - press a key on the console to abort

And when I said:
options     NINTR=43
I got again this message:

IOAPIC #0 intpint 29 -> irq -1
IOAPIC #0 intpint 30 -> irq -1
IOAPIC #0 intpint 31 -> irq -1

What shall I do to enable SMP?
