The exact error message was:
"Root-NFS: No NFS server available, giving up.".
First thinking about a misconfiguration on the BOOTP/DHCP/TFTP/NFS
servers, then I did some sniffing and discovered that the box wasn't
sending any ethernet packet at all.
The kernels used for thoses test was vanilla 2.4.10 and 2.4.9-ac7.

I attach the .config used for the minimalist kernel used.
For the screendump ... I'll do some with a digital camera on Monday
(or before if I happen to be at the office this week-end).
Which information can be revelant ? Ethernet devices driver (Intel
EtherExpress Pro 100, BTW) was loaded and IP stack compiled in.

I didn't try with 2.4.4 ... juste stock Linus 2.4.10 and Alan Cox's

Well, whynot, I'm sure I'll have to tweak the DHCP configuration somehow
later, but my first problem seems to be the kernel not even doing the
So a kernel image know to success on that could help. However ... I did
doublecheck the kernel options for the IP_PNP and NFS/NFSROOT.
