Urgent please, panic OpenBSD26 on 1300M RAM and two proc PIIIX.

[fde <fde@mgn.net>]

Hello,

At the time of the boot on the first diskette of OpenBSD 2.6
(floppy26.fs),
a panic grass appears !

The message is:
    "No-maskable interrupt, may be parity error".

This machine is Compaq Proliant 5500R, it contains 1300M of RAM and is
bi-processor Pentium III 500Mhz.

Did somebody connait it limits it in memory of OpenBSD ?

If one puts 256M of memory, OpenBSD boot on the diskette until A the
installation!
(with the two processors).

If one puts 1024M of memory, OpenBSD don't boot.

Thank you by advance.
