Hi all,

I am new on Cisco, and I have a 1812J, since I want to using the 256M RAM with 64CF card IOS.

So now I upgrade my Cisco 32CF Card, and now I just can buy the SanDisk 4GB card.

Then I am using my computer and CF Card Reader to just copy the IOS and SDM Express to the new SanDisk 4G CF card.

Later plug it in the 1812J and power up. all thing look good. But later I am stopped on the

rommon 1 >

Here are the error I am look from the Concole

Initializing ATA monitor library.......
open(): Open Error = -66
boot: cannot open "flash:"
boot: cannot determine first file name on device "flash:"

rommon 1 >

But I can boot up the 1812J from the old Cisco 32M CF Card no problems, what is wrong on it? Any step I am miss?

Thank you.

1.  If you use more than 2Gb CF then it will take approximately 20 minutes just to read.

2.  I wouldn't recommending using greater than 2Gb.

3.  Not all CF are supported.

Hi leolaohoo,

The boot time of the 4G SanDisk CF just fine like original 32M CF from Cisco, not need 20 minutes yet.

Just about 1-2 minutes is done!!!

This person is using 1811

I am higher model 1812J so I think that I can using the 4G SanDisk ....

[explorer1979Jimmy]

Hi all,

I final self fix it and can using the 4G SanDisk CF Card,

Let me share my experience there....

1. Using the old 32M boot up the 1812J

2. If the CF Light on 1812J not light, then make the 32M CF Card out then plug the 4G Card in

3. enable

4. format flash:

OR read the doc by Cisco

http://www.cisco.com/en/US/docs/routers/access/3700/software/configuration/guide/AppendB.html

1812 can support 4G CF Card no problems, I am using the Class C format.

Thank for all who help me there.

According to the Cisco spec sheet the max supported flash is 128MB. I personally would not trust going over that in a production environment even if I could get it working.

I do see something odd in your output......

I see a negative bytes available

Also if you add the two numbers together, removing the negitive sign it comes up as 315MB.....kind of an odd number.

Typical printf bug, nothing to worry about.

Hey Mike,

How are you doing?  Haven't seen you posting for a long time.

Should be fine.  (Dude, you should see some of the routers and Sup32/720 here.  I've got them loaded with 2Gb third-party CFs!)
