RE: ipxe.lkrn does not detect Atheros L2 network interface
Hello,

I've attempted to modify the src/drivers/net/atl1e.c file according your suggestion and recompile the module.

Well it did not work! And I still do wonder "How does it work from floppy IPXE"?

Ok, here what I get when I boot from the floppy

Code:
IPXE 1.0.0 (fd95c) .. Open Source Network Boot Firmware: -- http://ipxe.org
Features: DNS HTTP iSCSI TFTP SRP AOE ELF MBOOT PXE bzImage Menu PXEXT

iPXE> ifstat
net0: 00:24:8c:7c:54:dc using <NULL> on UNDI-0000:02:0.0 (closed)
   [Link:up, TX:0 TXE:0 RX:0 RXE:0]
iPXE> dhcp
Configuring (net0 00:24:8c:7c:54:dc)...... ok
iPXE> ifstat
net0: 00:24:8c:7c:54:dc using <NULL> on UNDI-0000:02:00.0 (open)
    [Link:up, TX:6 TXE:0 RX:7 RXE:0]
iPXE>

Well, in place of "<NULL>" I would expect to see a driver name or a chip id...

Now I run command "config" then I see

Code:
busid ............... 01:19:69:20:48
busloc ............. 0x200
bustype ........... PCI
chip ................ <not spcified)
ifname ............. net0
mac ................ 00:24:8c:7c:54:dc
.......
.......
gateway .......... 192.168.0.1
ip ................... 192.168.0.30
netmask .......... 255.255.255.0
dns ................. 192.168.0.1
domain ............ coguar.com
filename ........... pxelinux.0
next-server ...... 192.168.0.60

and if I boot through pxelinux.0 and chainload ipxe.lkrn I get following

Code:
IPXE 1.0.0 (fd95c) .. Open Source Network Boot Firmware: -- http://ipxe.org
Features: DNS HTTP iSCSI TFTP SRP AOE ELF MBOOT PXE bzImage Menu PXEXT

iPXE> ifstat
iPXE> dhcp
iPXE> ifstat
iPXE>

if I run command config then... all fields are listed as "not specified".

Does it look intersting, isn't it?

When I boot from floppy, somehow the network interface gets detected and configured although the chip is "not specified" as indicated by software.

What does it takes to include "alt2" driver into ipxe latest package?

Now about switching to iPXE completely.... well not so fast as I need to get it working before.

Currently in pxelinux I have an extencive number of Linux distributions installation and working on M$ Windows to make unattended install (currently through Debian's version of iPXE which is missing "cpuid" --probably I will download source and attempt to recompile it with "cpuid" enabled).

I looked through iPXE documentation and a little bit confused how to make "Menus" of same extension as I did in pxelinux.

The documentation for pxelinux is very well layed out in regard of format menues, commands which can be used in the menu, colors, position, VGA modes, images for background and some other useful information.

Looking through iPXE documentaion I found it also quite informative but lacking details regarding "Menu" -- is it possible to preselect VGA mode, position menu let say at resolution of 1680x1050 in right low corner, how an image can be included and changed with selected item from menu, and possibly other useful information on "configuring menu"?

I do not believe that I missed this information in the documentation -- the information on iPXE menu configuration is quite "brief". If you can give some pointers to an examples it would be great assistance.
