Ok after this took me over 3 hours to fully work out, I thought it was best I save others from the ball ache, I know its an old post, but this may help someone else out there :)
As well all know for what ever reason IBM decided not to release a Windows Disk Less Update for the 3.04
After creating lots of coasters attempting to get it going by exporting the floppy image and converting it to CD I stumbled onto this post (thinking for the first time ever magic iso had failed me).. my cds booted and like im sure many others got stuck at : reading the embedded controller program file.
The iso provided here for 3.04 also failed to work for me, at this point I was starting to lose my cool, and then I noticed if you scroll down the page on IBM ECP update you can get the older versions and it was there I noticed 3.03 had a disk less install (windows flash), I don't have a floppy drive and the CD iso method had bore no happiness.

So i tried the disk less 3.03 upgrade and would you adam and eve it, loaded first time no issue under windows...
Grrr Still no 3.04 but one step closer, it was at this point i decided to pick apart the 3.03 disk less installer and well well well, looks like it just used a floppy image, so i took out the 3.04 disk image I created earlier with virtual disk and replaced 3.03 update with my 3.04, stuck it all into a self running rar (exe) file and what ja know, the bugger works, stone the crows.
So here it is the disk less update (windows based) for 3.04 embu1r71.exe that IBM never actually made :)

And anyone who tells you that you have to do the ECP update before the bios is wrong, i went from the 1 but lowest rev bios and the 1 but lowest rev ecp, upgraded the bios first to latest and then got stuck on the ecp, that was until I found this solution.
WHY OH WHY IBM never made a disk less install for this and instead offer everyone a disk only upgrade for 3.04 is frankly beyond me, cus as I have proved it wasn't hard when I had the right tools and a little know how.
This release supports the following systems:
- ThinkPad R50, R50p
- ThinkPad R51 (M/T 1829, 1830, 1831 and 1836)(*1)
- ThinkPad T40, T40p, T41, T41p, T42, T42p
Note: (*1) Machine Type 2883, 2887, 2888, 2889, 2894 and 2895 of ThinkPad R51 family are not supported.
Obviously if you brick your system running this don't come crying to me, you run take the file and run it at your own risk, basically once the installer runs, follow the instructions and and for the love of god don't turn the system off until it completes. If you worried about a virus, go and get the 3.03 disk less and confirm for yourself the CRC for the exes in that self expanding rar is still the same, the only other file is the just the disk image. If your really worried make your own, but believe me its clean here is a scan result from virus total (0 out of 43 hits) :
