Avoiding probing a DEPCA card
I'm trying to install debian 1.2 from scratch on a machine with a DEC
EtherWORKS LC (DE100) ethernet card. I know from past experience with
Slackware that linux kernel probing will prevent the card working again
when rebooting MSDOG unless you power off first. So I was expecting
trouble.
To start with, the card isn't detected, and insmod wouldn't work because
the defaults were 0x200 and irq7 whereas the card's factory default
setting (which I stick to) is 0x300 and irq5. But I got that sorted with
the ethernet HOWTO and have "depca io=0x300 irq=5" in /etc/modules.
But when I select FTP access in dselect, I get
Connecting to ftp.mcc.ac.uk...
eth0: transmit timed out, status 0063, resetting.
and I have to ^C out.
I am booting from the custom floppy that I just made, and have tried
typing
linux root=/dev/hd4 reserve=0x300,16 ether=5,0x300,eth0
with either, neither and both of the options. I also tried substituting 0
for 5, just copying the example from the HOWTO.
Reserve evidently works as I can see various messages about addresses
being already allocated. But it prevents /etc/modules from installing the
depca module, and I can't insmod it either, because it's reserved.
Ether has no apparent effect. I thought it would override the Reserve, at
least, that is what section 10.1.2 of the HOWTO seems to say.
BTW the HOWTO refers in the next section to
/usr/src/linux/Documentation/networking/net-modules.txt and yet it's
highly unlikely that you're going to have access to that file at this
stage in the proceedings. Is the information contained therein (a list of
insmod parameters accepted by each module) available anywhere that is more
easily browsed? (I was fortunate in that the HOWTO happens to use io=
and irq= as examples in the text.)
