The only resources I found that mentioned this pointed to putting a new IOS file in flash with XModem. When I try to do that it bails quickly with an "invalid argument" error *I know the image is good because I've used it many times"
thanks for the replies. the flash_init, load_helper and boot commands didn't help too much since it would say flash already initialized and then refuse too boot anyway. After trying a bunch of different things I finally try to method of resetting a forgotten password (not because it had any relation to my problem but in hopes that it put the switch in a better "place". So, it turns out that when I held the Mode button down on reboot it still gave me the same error but I was finally able to view the flash: directory and, in turn, use Xmodem to upload a good flash image (the image listed in the flash: dir showed zero kb so it must've really gotten corrupted. After that it still took me some time to get it to change the environmental variable to point to this new image (even though named the same) by setting that after manually loading it instead of at "switch:" but that finally did it and so far no worries.
