K100d Firmware

Mate has a K100 and his firmware is V1.00,he wants to use sdhc.

I looked at pentax jp for a firmaware update and found 2, V1.01 and V1.02,now am i missing something or are they both the same??

v1.01

and

v1.02
http://www.digital.pentax.co.jp/ja/info/20060808e.html

and having just posted both urls i see they are!!
I got them from here

Can anyone explain? My mate is away on holiday soon and would like to take some of my sdhc cards with him. is there a differance between the 2 updates or not? if so which one do i use on his camera??

I dont believe there is a difference i have just updated from 1.00 too 1.02
believing 1.01 was just an older update

I used the one from here.

Went smoothly and have tested to confirm the sdhc compatability.

Make sure you use newly charged batteries before running the update.
