Hi,
I'd love to have one.
Thanks,
Ross

The IDE port has three address lines giving 8 16 bit registers directly addressable. Not all of them are decoded, there are some holes. I can't remember off the top of my head which ones, but I exploited that fact ten years ago to produce what was effectively an IDE-connected VGA card for the empeg, which could be connected to the IDE bus without interfering with the drives  Now, it may be that the problem is essentially that the converter is nobbling one or more address lines that don't affect the IDE port, being a non-decoded/non-used location, but the same lines mapped into the ethernet address space prevent it from working correctly. As I remember the ethernet controller uses a lot of registers, and it would only take one to screw it up completely. Also, I very vaguely seem to recall that some of the IDE operations are 8 bit only, although I may be misremembering that. So again, if the higher data bits had an issue that might not affect the IDE to the point of killing it completely, although this seems much more unlikely to me. The way we used IDE it used all 16 databits to get anything to/from the disk. All 3 address bits are used for the bottom CS (sector count, LBA address, etc). The top CS only uses the top addresses for the status register, but you still need all 3 address bits intact otherwise that won't work either as it's fully decoded in the drive. Nothing from ethernet lives in these holes. The only way I can see anything bad happening here is if the converter is pulling on address or databits when both IDE CS lines are inactive. That *would* cause problems. ...but one sanity check first. Are you sure that you loaded the mk2 disk image? Got a boot spew? That might give more clues.

Hi,
Yes, the boot was correct. The partitions were all created correctly. I was even able to fix the Tags files through a commanded database build. Which almost always doesn't create the Tags files (the only one that is created in the /empeg/var directory is the config.ini file) for large disks (both PATA and SATA).
It was the same as if I had created a set of 250GB PATA disks or a SATA disk (1TB drive with the other converter that nearly works).
Thanks,
Ross

Hi,
I guess the above statement is to say that you are tired of the thread. Correct?

Quick note on the empeg. On a recent episode of This Week in Tech, Leo Laporte brought out an empeg during the show to talk about it. He got a key fact about it wrong (that it needed a hard drive in the trunk - what was that competitor he's thinking of?), but it was great to see the old empeg get some more time in the sun. He keeps it in his little computer museum, and it's actually one of my two stereos, that I gave to him on my trip to SF last year

Ah yes, the PhatBox. Boooo I do love that they have a 128MB USB stick MP3 player for sale on their site. Too bad they're sold out, because I'd really have liked to pay $79 for it.

Phat Box. Kenwood Music Keg. The Neo mp3 could be fitted anywhere you've found enough space for it in your car, but most of the times this was also in the trunk.

Hi,
I guess the above statement is to say that you are tired of the thread. Correct?
Ross Just the opposite! I love how the threads on this board can detour wildly into hardcore technia and then take another swerve in other directions, too. This thread in particular is an excellent example. Having said that, though, I've probably just killed it. Hope not.

Ross Just the opposite! I thought Ross was making a pun, because the kitten was sleeping. And Tony +1'd it, because it's a kitten.

haha- Yah, I realize it could be taken that way, but didn't want to leave it to chance! Also, I never thought of the kitten as actually sleeping. I guess I have always been taken along with the implied meaning in that lolcat.

Hi,
I thought it was a very creative image.
Sometimes, I go too much into the details. When tha happens, just yank on my colar and tell me to "sit" in a stern voice.
That should work.
Ross

You should learn more about this popular 'lolcat' meme that the kids are doing these days.

Sometimes, I go too much into the details. Meh. It's important to record details, particularly when the only thing left supporting a product is the community (and a small one, at that).

Well done, Hugo. I enjoyed the talk very much.

I think they film them, so when it's up I'll post the link (if anyone else really needs to get to sleep that badly ). Thanks for coming Stu, and bringing the empeg bits! The venue is kinda interesting, I was working from there for a couple of months and it's very social if you want it to be... it's a bit hard for hardware development though because you can't leave anything set up overnight.
