config(8) not saving modifications?

[BooK <book@netcourrier.com>]

Hello,

After upgrading from OpenBSD 2.7 to 2.9, I changed the parameters for my
NICs to something that could actually detect them. My system is a
486DX4/100, with three 3COM NICs (drivers ep and ec).

After saving the changes in config, they don't appear in the kernel when I
look at it with boot -c and find, though they look fine after boot.

Right know for each reboot I have to boot -c to correctly configure that
NIC.


Here is how I did:

Since I have ec0 and ec1, I had to add ec1 to the generic kernel, and
change the configuration information. (the last one is ep1, detected
correctly)

Here is the config -e output.

OpenBSD 2.9 (GENERIC) #653: Sat Apr 28 13:57:59 MDT 2001

After the new kernel was saved I rebooted. But the new card was still not
dectected. After a little more investigation, I found a strange line in
boot -c...

User Kernel Config
UKC> find ec
130 ec0 at isa0 port 0x250 size 0 iomem 0xd8000 iosiz 0 irq 9 drq -1 drq2 -1 flags 0x0
131 ec1 at isa0 port 0 size 0 iomem 0 iosiz 0 irq 0 drq 0 drq2 0 flags 0x0

It looks like the changes have not been saved, though the cloned device is
here.

With the verbose boot option, I can read that 

>>> probing for ec0
>>> probing for ec0 succeeded
ec0 at isa0 port 0x250/16 iomem 0xd8000/8192 irq 9
ec0: 3Com 3c503 Ethernet (16-bit)
ec0: address 02:60:8c:a9:9d:e9
>>> probing for ec1
>>> probing for ec1 failed

If I enter the necessary information with change ec1, the system detects
both ec0 and ec1.

>>> probing for ec0
>>> probing for ec0 succeeded
ec0 at isa0 port 0x250/16 iomem 0xd8000/8192 irq 9
ec0: 3Com 3c503 Ethernet (16-bit)
ec0: address 02:60:8c:a9:9d:e9
>>> probing for ec1
>>> probing for ec1 succeeded
ec1 at isa0 port 0x280/16 iomem 0xc8000/8192 irq 5 drq 0 drq2 0
ec1: 3Com 3c503 Ethernet (8-bit)
ec1: address 02:60:8c:9e:13:72

Does anybody know why the device I cloned cannot retain the configuration
information between boots, even though I saved it with config -e? Does
config actually save the information? Did I miss something?

I hope I won't have to recompile the kernel, since on this 486 machine, it
can take a while (with no cdrom, a nfs connection to the sources and 16 Mb
of free disk space (out of 250), compiling a kernel is a challenge in
itself... :-) )

	Thanks in advance,
