NIC Jumper settings

[per]

I recently got a CN600E rev B NIC, however I don't know the jumper settings. Some of them are obivous, but there is someone I can't figure out.

what I'm asking for is those jumpers:
JP1
JP4-11
JP12-15

I would be happy if anyone have experience with this card.

BTW, does anybody know why it is 16Kb SRAM on the controller?

Cache RAM?

If it is RAM it is probably buffer RAM for incoming and outgoing packets.

If it is an EPROM or ROM, then it is for network boot support.

As you see on the picture, it got a ROM socket too, but it's empty.

Do you have a driver for this card? I think the hardest thing about network cards is finding drivers. ISA cards are getting rare but even then I find it easier to match the card to the driver than the other way around!

I actually got a driver (yes, it took me some days to find it. avalible here: http://www.updrivers.com/drivers/Ne...S_2_DOS_Windows_NT4_NT351_98_95_31/15769.html ), and the guys at C-net Tech. was so kind to provide me a dump of the 16Kb RPL Boot ROM (NetWare compatible, at least).

The SW1 cecoding formulas are:

I/O BASE ADDRESS (Size = 0x20):

A-	5	6	7	8
Sw	SW1/1	SW1/2	SW1/3	SW1/4

Sw	= On or Off
On	= 1
Off	= 0

		8
	0x400 - Σ(2^(A*Sw))
	       A=5

BOOT ROM BASE ADDRESS (Size = 0x4000):

A-	14	15	16	17
Sw	SW1/5	SW1/6	SW1/7	SW1/8

Sw	= On or Off
On	= 1
Off	= 0

		   17
	0x100000 - Σ(2^(A*Sw))
		  A=14

All numbers without the "0x" prefix are in decimal. numbers with "0x" prefix are in hexadecimal
