The information in the V3 flash thread is great, anyone reading this post should have read that thread first.
Second, in my experience no single post in this thread solved completely all the problems I encountered, however mixing and following the evolution of the thread did the trick. Cumulatively this IS the thread to get a V3 working
This post is feedback on what worked and what problems were encountered, it's intended to help supplement other posts here. In my case I ordered a $39 +$8 S&h 1.3GB laptop drive from CompuGeek... really not a bad deal.
I downloaded Dolly, had a copy of the I-Opener image disk, which was unzipped.
First problem, I run W2K usually exclusively, definately Dolly is a W98 DOS mode program If you are a W2K person with NTFS hard drives, this presents a problem, solution was to dig up an old IDE hard drive with W98 on it.
Second, Dolly disagreed with my autodetected sector count. That is the number of sectors in the BIN file was more than Dolly wanted to copy to the hard drive. The solution was to set the detection type to normal from auto (why this works is unknown to me), but it did. Thus on the non I-Opener PC, setting all CHS information AND setting normal resulted in Dolly happily setting up the drive.
The initial post in this thread, indicates setting the BIOS to 490,2,65535,489,32,NORMAL on the I-Opener, I'd suggest an identical setup on the PC creating the DOLLY copy (note the NORMAL, it IS imporatnt in my experience).
Partition Magic (4.0) showed 4 partitions on the DOLLIED drive, after successful copy.
Great, ok so now my hard drive is formatted, and I go to the I-Opener... try to boot, set to boot D, and it fails... at first tried changing the master/slave setting on the hard drive, tried C and D, didn't work.
What did work was turning C off, manually configuring D and booting with C only (I am not certain if this is the only solution, but it worked for me, your milage may vary). I am uncertain, but it appeared to me the C only was required, I could have tried more but didn't, I did try various settings and on failure would load factory defaults. If stuck, I'd suggest loading factory defaults, then configuring the BIOS settings as per the above.
Hearing the "male" voice was great, the laptop harddrive made just enough noise for me to know without any doubt that the "voice" was coming from it and not some darned sandisk. I knew on hearing it, flashing wouldn't be far behind.
Which brings me to the flash... there is a post about the need to put a ./ in front of the flash command line... it's true... and on doing that it worked.
Once flashed, a new set of problems became evident... which I'm starting another thread about (relating to trying to get W2K up and running). It's great to have this board, I hope this post helps anyone still stuck.
