Hi Simon,

Then it is probably the classic RTL8029 (10mbit) or RTL8139 (100mbit)
chipset. It should be possible to use generic NE2000 / NE2k drivers
with those, but it is often better to use drivers for Realtek cards.

To find out which packet driver you need, you can use PCISLEEP
(if it is not part of your FreeDOS install, just search the web)
to get a list of PCI / AGP / PCIe / onboard-PCI devices in your
PC. Look at the devices in the "network" category. You can search
the web for the device ID, but often you can already guess the
type from the number. A nice lookup service is the PCI IDs page:
http://pci-ids.ucw.cz/iii/?i=10ec8139 for example tells you that
device 10ec:8139 is RTL-8139. The subsystem ID would show you
which brand of RTL8139 based device you have, but this makes no
difference for the choice of driver: All RTL8139 should work
with the classic RTSPKT 100mbit driver which can be found in
various collections like the Sioux one mentioned by Fabien.

As Fabien said, the settings for your home LAN go into wattcp.cfg,
but you can often get things working with a very simple wattcp.cfg
which only says "use DHCP", more or less. There are explanations
about which variables can be set and to which values inside the
default wattcp.cfg file :-).

> I don't want to have to reinstall Freedos just for the new hardware.

No problem, you only have to replace the packet driver.

But you are right, there is some batch file in the packet
driver package which automatically selects a driver. You
could try to use FDPKG to remove this package and install
it again to automatically get some updated configuration
after you change to new network hardware. Please ask
Blair (blairdude at gmail.com) if you cannot find out
how to trigger this automatic setup. No matter if it is
you or Blair who found the answer, please tell on this
list how it works as soon as you know :-).

You can also use bootdisks like www.netbootdisk.com or the
www.veder.com/nwdsk/ which contain a pile of packet drivers
and some mechanism to automatically decide which driver is
suitable for your hardware. After booting nwdsk or netboot-
disk, you can look at the generated config and copy the
relevant settings to your FreeDOS box :-). If you cannot
find config in files, you can still do "mem /d /p" or use
similar tools to find out which drivers got loaded :-).
