-The de425/de434/de435/de500 driver in this distribution is designed to work
-with the Digital Equipment Corporation series of PCI/EISA ethernet cards
-(DE425, DE434, DE435, DE500) and with all kernels that support PCI.
+This driver has been upgraded to include generic DECchip support through the
+use of the on-board SROM that is found on all DECchip cards except for the
+DC21040. The driver will work with the following set of cards and probably
+more:
+
+ KINGSTON
+ Linksys
+ ZNYX342
+ SMC8432
+ SMC9332 (w/new SROM)
+ ZNYX31[45]
+ DIGITAL EtherWORKS PCI/EISA (DE425, DE434, DE435, DE450, DE500)
Auto media detection is provided so that the media choice isn't compiled in
-and is flexible enough to be able to reconfigure on-the-fly. This feature
-hasn't been included for the DE500 unfortunately, due to a potential patent
-dispute. When I get around to implementing the autosense algorithm by myself
-(which could legally be difficult to prove since I'm part of the group that
-has implemented the patented algorithm) you'll have an auto speed selection
-for the de500. If you want the auto speed feature yell at Digital. If enough
-of you do things might change.
-
-The ability to load this driver as a loadable module has been included,
-although I don't recommend its use with PCI, since PCI dynamically allocates
-where the card will go at boot time (i.e. the card would have to be present
-in the system at boot time for its address/IRQ to be assigned).

+The ability to load this driver as a loadable module has been included and
+will now load (and unload) as many DECchip cards as it can find and

measurement. Their error is approx +/-20k on a quiet (private) network and
also depend on what load the CPU has, CPU speed etc.
-ZYNX and SMC cards, which use the PCI DECchip DC21040, are not specifically
-supported in this driver because
-
-a) I have no information on them.
-b) I cannot test them with the driver.
-c) Donald Becker's 'tulip.c' driver works with them....well one person says
- they do and another says they do not, so take your pick!

-This driver can be made to work with the ZYNX (and may be the SMC) card by
-setting a compile time flag (IS_NOT_DEC) in linux/drivers/net/CONFIG
+I've had reports that Alphas can get 80+Mb/s when using 100BASE-TX and
+similar figures for 133MHz Pentium Pros.
