CIS should be written into the non-volatile memory of the card, just like
the PDA and the non-volatile firmware.

You should be able to do it using either the same flash.exe or prism2_srec
and a specially prepared srec file containing the CIS you want to flash.

CIS should be in the s-record format.  You can find an example in file

If you unzip that file, you will find file BROMAX5V.HEX.  The CIS is
written at address 0x3EFE00.  You should convert your dump to the srec
format.  You can use objcopy for that.

You don't need the PDR at the end of that file (line containing FF000000).
It simply instructs the flash utility to get the MAC address from the PDA.
