#DOS
@Greg_Gauthier asked for my configuration details... so here it is.

I put the Intel pro1000 drivers in a C:\NET\PRO1000 folder. I added a net.cfg file in the same folder that has:

Link Support
Buffers 8 1514
MemPool 8192
Max Boards 4
Max Stacks 4

Link Driver e1000odi
slot C8
; Remove the semi-colon in front of the frame type you will use.
; This frame type must match what the NetWare server is using.
; FRAME Ethernet_802.2
; FRAME Ethernet_802.3
; FRAME Ethernet_SNAP
FRAME Ethernet_II
FRAME Ethernet_802.2
protocol IPX 8137 Ethernet_II
protocol IPX e0 Ethernet_802.2

NetWare DOS Requester
FIRST NETWORK DRIVE = F
NETWARE PROTOCOL BIND NDS

; If you know the name of your preferred server, remove the

;preferred server =

Then I have the following changes in C:\fdconfig.sys:

... (skipped some lines) ...

MENU 6 - Load FreeDOS with network drivers

345?SHELL=C:\FreeDOS\BIN\COMMAND.COM C:\FreeDOS\BIN /E:1024 /P=C:\FDAUTO.BAT

Then my C:\fdauto.bat has (many lines omitted here for brevity):

...

set WATTCP.CFG=C:\NET\
...

if "%config%"=="6" goto NET

if "%config%"=="5" goto END

...

goto END

:END

My C:\NET\MTCP.CFG file has a static IP config:

PACKETINT 0x60
IPADDR 192.168.1.85
NETMASK 255.255.255.0
GATEWAY 192.168.1.1
NAMESERVER 192.168.1.1
MTU 1500

And C:\NET\WATTCP.CFG is similar:

my_ip = 192.168.1.85
netmask = 255.255.255.0
nameserver = 192.168.1.1
gateway = 192.168.1.1
MTU 1500

Don't HAXXOR my super-secret IP address! 🤪
