How do I set my ASA 5510 for 1Gb

Hi All,
I'm trying to figure out why my ASA only reports being capable of 100Mb on e0/0 and e0/1.  I have read that if the device it is plugged into (in my case, a Dell PowerConnect 2748) is 1Gb capable, it will run at that speed, but am finding this to be untrue (at least in my case anyway).  The PC2748 is a Gig switch (all ports are gig by default), but am still not seeing 1Gb within the ASA (sho int).
ASA# sho int e0/1
Interface Ethernet0/1 "INSIDE", is up, line protocol is up
  Hardware is i82546GB rev03, BW 100 Mbps, DLY 100 usec
        Auto-Duplex(Full-duplex), Auto-Speed(100 Mbps)
I've tried to manually set the speed but to no avail (config t | if e0/1 | speed 1000). When I try this, I get an error stating that 1000 is not an option (options are 10/100/Auto).

Am I missing something?

Is the intf you're connecting to gigabit capable?
Have you tried running the "Auto" option?

Let us know.

And also.... Just an FYI...
You will need to purchase a security plus license(if you havent already) to get gigabit speed on the asa-5510 for ports e0/0 and e0/1.

Yes, the int I'm connecting to is on the 2748 and all ports are gig (I double checked the specific int settings in the gui). Also, I do have the sec plus license:

What version of the software are you using?

I remember returning an ASA once because it had no Gb interface.
I'd got those when I upgraded the software. Can't remember what software version it was implemented (7.x something) though. If you're able to, just go to 8.2.x should do the trick.

Ah, okay... craigbeck's link may explain what is going on...
I ran into this myself. Gigabit was introduced in 7.3(2). But it was left out of 8.0(2).
I cannot speak for 8.0(3) - but I know it works as stated in 8.0(4).
That is with a Security Plus licence you can configure "speed 1000" on e0/0 and e0/1 (it will autodetect it as well).

I am currently running 8.0(2) - that figures.  I'll upgrade to 8.2 this weekend and see if that changes anything.  I'll split points between craigbeck and erniebeek because you're both saying the same thing (although un-verified to be correct as of yet).  
Thanks all!
