Network trouble - 3C905CX-TXNM

Hello Network Experts,

I have no experience with QNX nor UNIX and am trying to evaluate QNXRTP.

Defaults were used during installation into an NT box. It boots from
floppy into
photon without trouble. But I can’t seem to communicate with any other
hosts on
the network. I can ping 127.0.0.1. I can ping the box’s own IP. But
when I try to
ping the router or other machines I only get “no route to host” or “host
is down”.
I can’t ping this box from other machines either. When in NT, this box
has no
difficulty with the network.

I have tried using DHCP and manual settings, with no change in the
results.

Upon bootup nicinfo returns:

Media Rate … 0kbp/s half-duplex UTP

I saw a newsgroup article that suggested using the following io-net
command to fix the rate number.
This is what happened in my case:
#slay io-net
#io-net -d el900 speed=100,duplex=1,verbose -p tcpip
Found device: (10b7, 9200 at index 0)
Caps (72a2). Card is a 90XB
media options: 1000
el900_init_phy: speed: 100000, duplex: 16
PHY found at address 24.
Media options: a
Internal Config: 1800000
100BTFD
Setting duplex on
Link down 0
Link up 0 (100bTFD)
(The ‘#’ prompt doesn’t return here until I hit a key.)

The switch that the box is connected to is 10/100 capable.

Subsequent nicinfo yields:
3COM (90xC) 10BASE-T/100BASE-TX Ethernet Controller
Physical Node ID …ADAD00 000000
Current Physical Node ID…ADAD00 000000
Media Rate …100.00 Mb/s full-duplex UTP
MTU…1514
Lan…0
I/O Port Range…0xE800 → oxE87F
(All other entries are ‘0’)


ifconfig shows:
lo0 flags=8009<UP,LOOPBACK,MULTICAST> mtu 32976
inet 127.0.0.1 netmask 0xff000000
en0 flags=842<BROADCAST,RUNNING,SIMPLEX> mtu 1500
address: ad:ad:00:00:00:00

I would like to include more diagnostic info but since I also get the
following message
at bootup,

“Unable to mount a dos file system… (Corrupted file system detected)”

I have had to manually type everything. (Can’t see files created in QNX
from NT.)
This is strange because there are no NTFS partitions in this machine,
only FAT.

If anyone can help me get this thing onto the network I would be
grateful.
Thank you all.

I have the same issue ADAD00 000000 is NOT a valid mac address

The 905CX adapter has a new ASIC that has slightly different timing then the
905C adapter. I have been able to get the CX adapter to work most of the
time by specifying the mac address.
#io-net -d el900 mac=XXXXXXXXXXXX speed=100,duplex=1,verbose -p tcpip
Where XXXXXXXXXXXX is the mac address of your adapter in hex. The first six
digits should be 000103

I boot a msdos disk and run the 3com install program to find the mac
address (under the info tab)
