[c-nsp] Cisco 1720 ADSL WIC not being detected

[Raz]

Hi,

 I am trying to Install an ADSL WIC, on 1720 with an old image, as I
read on Cisco.com, 1720 series routers need y7 series images to detect
ADSL WIC cards, Now the problem I have got its router's flash memory is
8 MB, IOS images for y7 series I have got all exceed 8 MB, is there some
other way to get around this problem. ADSL card is installed on WIC 0.

Regards
