Here's what I got on my COMPAQ 575:
0000:0400 F8 03 F8 02 E8 03 E8 02-78 03 00 00 00 00 5F 03
........x....._.
(This is just the first line, there are eight lines. 0400,0410,0420 thru
0470)

Mine are all free. I get:
0000:0180 00 00 00 00 00 00 00 00-00 00 00 00 00 00 00 00
This is the first line after I enter d0:180. There are 8, and only
the first, seventh and eighth lines are free, the others have items
like this D0 9B 00 F0 DD, etc in them.

My Netdial 1.3 .bat file sets up epppd like this:
@lh epppd base 0x2F8 irq 3 pktvec 0x60 38400 asyncmap 0
crtscts
I have wondered if Arachne could use such a line instead of:
Connection @epppd.exe>>PPP.LOG
and have a better chance of installing the packet driver.

I have Arachne set up this way in arachne.cfg
when I use the Netdial 1.3-Arachne setup:
[profile]
Profile aracdial.ACF
Connection READY
Hangup @termin.com 0x60>NUL
(and)
[tcp/ip]
IP_Address %MYIP%
IP_Grab IP address set to
NameServer 206.156.254.2
AltNameServer 206.156.2.0
Gateway 0.0.0.0
AltGateway 0.0.0.0
Netmask 0.0.0.0
TCPconfig LANTCP.CFG

Guenter,
Forgive my tardyness in running the experiment, I got the FLU, and was unable to
do it for a few days. I have my notes as to my results inserted in
the original instructions above. On the Compaq 575 am able to load
a packet driver using Netdial 1.3, and then I go to Arachne with a
little .bat file adapted from the Bobcat bcatdial.bat.
Netdial uses 0x60 also. I have this on three machines, and also
have the usual Arachne-epppd setup also, selected by two .acf
files on each one. Only on the COMPAQ do I have trouble getting
the usual Arachne-epppd setup to work, so as just mentioned,
I had to rig up the Netdial-Arachne combo to get a successful
connection to the internet.
Before I made that combo, I got Bobcat to run on the COMPAQ,
and when Bobcat's epppd had no problem with installing packet
driver at 0x60, I knew what I could do to get Arachne up and
running.
I have epppd loaded high on all machines, so have about 615K
free conventional memory for Arachne, which works very well.
Any comments and suggestions will be appreciated.
