Subject:   [2.1.5R] problem detecting wdc0 and wdc1 with Asus P/I-P6NP5
Message-ID:  <>

Hi everone,
    Just got a new Asus P/I-P6NP5 board with PPro 200 with the following config:
Adaptec 2940 PCI SCSI-2 interface, SMC Elite-16 NIC, an S3 video card, 32M
Quantum 850MB IDE drive connected to the on-board IDE interface 1, a
Micropolis 2.1G
SCSI-2 drive and NEC 6X CD-ROM drive on the Adaptec 2940 card, and finally
an ET5025

    The fishy thing is that, when I boot up the system using the boot.flp floppy
image, at the CMOS BIOS phase, the Quantum IDE drive is detected as slave
drive on 
primary IDE interface even though the drive has NOT been jumpered to mark it
as either
master or slave and my understanding is that when there is only one such IDE
drive, it defaults the drive setting to be master automatically, and
apparently that is not the case.

    Secondly, when the system actually loads in the floppy boot kernel, it
fails to detect the wdc0 and wdc1, and therefore I cannot get to the IDE
drive at all. The following are the probe messages:

wdc0 not found at 0x1f0
wdc1 not found at 0x170

wdc0 and wdc1 are at IRQ 14 and 15 respectively according to the motherboard
BIOS report. I did the following as suggested by one of the doco in the boot
up menu using
fd(0,a)/kernel -c :

port wdc0 -1
port wdc1 -1

but it still fails to locate the 2 controllers.

    Please can any one offer any help ?

    Thanks in advance.
