Hi.  With the help of your great HowTo, I've managed to flash my
Prism2.5-based Belkin F5D6001 (component ID 8013) from P1.1.0/S1.4.2 to
P1.1.1/S1.8.0 using the Winupdate utility.  I tried to flash S1.8.3, but I
could only find an R series file, and Winupdate doesnt support RAM
loading... meaning I ended up accidentally flashing primary only... was
worried for a second, but Winupdate allowed me to reflash P+S no problems.

Thanks again for your great HowTo and collection of resources, couldn't
have done it w/o your info.
Best Wishes,
Greg M.
