FlashCard is a PC/AT adapter card which puts a Flash EPROM into your PC. Such
a Flash EPROM is like an ordinary EPROM but it's electrically erasable. Flash-
Card can be used to substitute the bootrom EPROM on a network card, as for the
processor it doesn't matter if the ROM is on a seperate adapter card or on a
network card. It's main features are:

	- Provides up to 128 kB of EPROM space, selectable in steps of 32 kB
	- Easy erasure, no need to buy a UV lamp
	- Easy in-system programming, no need to buy an EPROM programmer, and
	  to unmount the system's cover

So you can use FlashCard for the bootrom if your ethernet card doesn't provide
the ability to use EPROMs with 32 kB or more, or if you just want the ease of
use. However, there is no PCB layout available yet, so you should know how to
work with a solder iron on a PC prototype card.

The flash.exe program can be used to program the FlashCard. It is currently
only available as a DOS application. Direct memory access is not easily
portable on UNIX systems (volunteers welcome ;-)). The command line syntax
is:

		flash <base segment> <file name>

The base segment address is given in hex and specifies the selected base
segment of the Flash EPROM. Note that when running 'flash' there should be
no memory manager (like himem.sys or EMM386) installed under DOS. 
The file name should be the path to the image.rom file, which contains the
bootrom executable. There is no need to convert this file in any way (like
into Intel hex format as for many other EPROM programmers).
