Laptop is the faster way to update a MR, only few seconds for a full flash, but I was able to do that only under win98se (no way with xp), and not all PCMCIA contoler work... I try on a lot of laptop, only non-cardbus work fine in my case.
If you can recycle an old pentium pro laptop, this would be the better way.
I am able to program my MR usign laptop and it is really fastest way that I know. But I have some question. I would like to reprogram my MR (1.14) to MRv(2.15). Can I do this using laptop and proper upd file? Will be possible downgrade later MRv to MR without CAS interface?
