etherboot 4.1pre1 released

[Ken Yap <ken@nlc.net.au>]

I have incorporated the fixes sent to me since 4.0 was released. You
can get the sources at

	www.slug.org.au/etherboot/etherboot-4.1pre1.tar.bz2

Note: a bzip2 file, not gzip. There are no new features, only bug fixes
so please don't treat this as a stable release.  Could testers please
verify the following:

1. Answering N to Boot from network? allows disk booting of Windoze.

2. The eepro100b driver autoprobes correctly.

I have added code to try to identify the NIC with the ROM mounted so
for PCI NICs please report the first couple of lines printed out after
activation, which should be something like:

ROM segment 0x%x length 0x%x
Found %s at 0x%x, ROM address 0x%X

The first line will print the right address only when run from a ROM
of course.

Here are the changes incorporated:

+ Patches by Andrew Coulthurst for eepro100b.

+ Patches by Doug Ambrisko for booting Windows95 after answering N to
the boot from network question. Added conditional code to cope with
broken DHCP server and TAG 128.

+ Put version and driver identifier at end of ROM image if it fits,
to help identify ROMs in future.

+ Capture ROM segment address and length to help choose between multiple
NICs later.

+ Don't clear all of memory because it will destroy return address
on stack.
