How To Stop NIC From Looking For DHCP Offers?


P

(PeteCresswell)

StarTech PCI-x network card, "Realtek RTL 8111B/8111C/8111D Giga
Ethernet Controller v2.21 (090908).

Got two of these puppies in my XP box - neither of which will
ever be connected to a router or switch. (they're used to
connect a couple of external "HD HomeRun" tuners).

But at boot time, each one goes on-and-on looking for DHCP
offers, finally giving up with:
"PXE-E51: No DHCP or proxy DHCP offers were received"
"PXE-MOF: Exiting PXE ROM

The BIOS screen for these things is *really* sparse and I don't
see anything there that promises to turn this behavior off.

I'm thinking maybe Control Panel | Network Connections | (card).

But there are so many props that I'm kind of boggled by them all.

Anybody know if there is a property lurking in there that will
tell the cards not to solicit DHCP offers at startup?

Something else?

Which motherboard ?

Would your add-in cards, happen to be using the same chip as the
onboard Ethernet ? Or are they different chips ? Sometimes,
the same option ROM, can be used to control multiple identical
cards (Adaptec cards do that).

Option ROMs are responsible for this behavior. Option ROMs
exist inside the main BIOS chip, and support things like
the onboard LAN chip (PXE), onboard RAID (extended INT 0x13
boot) and so on. Option ROMS also exist on add-in cards.
For example, a video card has a VESA ROM, which tells the computer
about the standard VESA formats (gives the 640x480 screen for the
BIOS). The video card ROM is around 64KB. Add-in LAN cards,
may have PXE in their onboard ROM.

If a card has the ROM physically removed, that can stop the
ROM from loading. (The LAN card I just bought, has two
ROM locations - the big DIP socket is empty, but a serial
EEPROM is present, with code in it.) The ROM loading feature
can also be globally disabled, but that can have side effects.
If you were used to booting off a RAID for example, and disabled
all add-on ROMs, that would mess up the feature you need for booting.

Not sure, but perhaps you could try:

Interrupt 19 capture [Disabled] # 19 decimal = 0x13 hex

as a test.

On my motherboard, my LAN chip has a separate control for
disabling the ROM (and stopping PXE). I think I've run it,
from day one, like this. But settings like this, have
no influence over any other added cards.

If you assign it a TCP/IP address then it won't go looking for one.
After you get to Control Panel -> Network Connections -> Card, look
for "TCP/IP" in the middle box (may have to scroll down), double-
click on it, then click the box labeled "Use the following IP
address". Set one card to 192.168.1.10 and set the other card to
192.168.2.10. Set the Subnet mask to 255.255.255.0. This should
keep it from soliciting an address via DHCP.

Did that from the start.

Now I'm wondering if I am mis-interpreting the message from the
card's BIOS. Maybe it is looking for something else.

The options are in the *device* BIOS

note: it is *not* the mobo bios nor is there any setting in Windows to make
the adjustment

you need to enter the device's options and diable the network boot option

Maybe it not from BIOS!

But from the Start up on it Systems
Like SYS.INI

Or a WIN.INI
