I wasn't sure about running jack of diamonds firmware update on the netglobal psion 10/100Mb card so I emailed Ositech and Psion for advice. I had these unhelpful replies:
An Ethernet card does not have 'firmware', so you cannot run a 'firmware update' on it.
Running the Jack of Diamonds firmware update (JDCELLxxx) on any PCCard other
than an Ositech Jack of Diamonds could risk damaging that card.
The Psion Netglobal card is not an Ositech Seven of Diamonds. Ositech does
manufacture some products under OEM, this is one - you should contact Psion
regarding any problems with this card.
Ositech are our technology partners for the gold card netglobal range,
however the driver & hardware name of the card are different to an Ositech
I am afraid that I cannot recommend that you use a program which may try to
overwrite the information on the card changing the card to Ositech card.
This may cause the card to stop functioning altogether.
NB I think there's a wrong tree here and were barking up it: This is not a ethernet/modem card it's just an ethernet card.
