I am not familar with the 3548 but you need to load the firmware back onto the flash.  In Cisco world you have a ROMMON that you can use to xmodem transfer the software back onto the device if you happen to erase everything like you seemed to have done. On my 6200 when you first power up the device with a console connection it gives you the option to enter the Boot Menu.  You should have an option to load an image via XMODEM if the 3548 has a similar Boot Menu.
Hello again, Well, due to either complete exhaustion, newbie-ness, or a combination of both, I managed to do the Erase FLASH command. Now when it is booting up, it tells me that both image files are corrupt or missing (I can't remember at this moment). The only files Dell has for on the product page is a file for firmware and a file for a driver (also a program and a xml file). I was wondering if there is another place I can look to fix my problem that I so gracefully created?  Thanks
