One thing that ~seems~ different since disabling Legacy mode: The menu after doing F8 during boot to get the boot menu now has "2.0 PMAP" after the Kingston choice. I say ~seems~ because it is possible that I just hadn't noticed it before, but I do notice it now.

It is indeed a 4G Kingston DataTraveler, but it never had any data encryption on it that I know of. I'll try the BIOS setting next..... OK, the setting was Legacy like you thought. Will now remove stick from laptop and try it in desktop again..... OK ... given this and your other replies, looks a bit more complicated than I first thought. Yes, the Kingston sticks use the same core for their memory whether or not they have the encryption and the SCSI trick at the head of their access. The issue appears to not even be related to the format on it, but possibly deeper. I'm thinking that the pass0 isn't being handled properly here by our kernel since pass0 handling is ... well ... pretty old and should only appear for old SCSI hard disks. BIOS should handle that as umass0 instead in BSD kernel design jargon. Your machine is getting told that it's a SCSI drive somehow. And given that it's happening there to you, obviously we're going to see this trick again. I was expecting to just hand you a copy of the older USB format, but I suspect we need to do a kernel tweak on our end to step around that. Each of our betas is new kernel code and I suspect we've got a Bronx handshake going on with that machine that manifests itself on the USB ports as they designed it which of course wouldn't affect a DVD since that's "ATA" stuff. Bottom line, working on it ... need a little more time to figure out "What do." Something that would help would be to boot up KNOS from the DVD on that machine, but have that stick plugged in before you start it up. Then email me the diags from it so I can see what the interaction is there ... something weird's going on and I'd like to pin it down.

Oh yeah ... another clue here ... should show up as an RMAP, not a PMAP but I doubt there's any provision in your BIOS to fix that. How OLD is that motherboard?

Will do - will it matter if the stick is 32bit and the disc is 64? I have both versions of disc, but only 32bit version of stick.

According to the system info program SIW, the BIOS Date is 06/30/2006 so that would be a rough guesstimate for the motherboard.

That sort of settled itself - you had suggested I make the 64bit disc in the first place because the 32bit disc would not boot on the desktop - and it still doesn't. But the 64 did and the diags booting-off-the-disc-with-the-stick-in is on its way.

well rats. No joy after disabling usb Legacy mode in BIOS. But, at least I got a little more of the info before the reboot: Fatal trap 12 : Page fault while in Kernel mode . . . Panic : page fault cpuid = 0 uptime 11 seconds Cannot dump. Device not defined or unavailable. Automatic reboot in 15 seconds...... Let me know how that fix works out for you ...

Sorry for the delay.
Am now booting knos3/64 on the desktop from the disc with the stick in as requested and will send the diags as soon as its ready. [writing from knos3/32 on notebook]

knos3/64 booting from disc w/stick in on desktop diags is on its way.

knos3/64 booting from disc w/stick in on desktop diags is on its way. Thanks for that! I forwarded all we had the last time to the kernel people and there's been numerous changes which will show up on our next release somewhere around the first week of February. And I mean *major* changes. Don't feel bad about the delay on your end, I've been kind of AWOL myself because there's just been SO much going on with this upcoming next build that I haven't had time to escape the sheer volume of new coding for what's coming. The changes will be *quite* major in this next one, and many of the issues we've seen appear to have been solved. Then again, we won't know for sure until the next release is in everybody's hands ... but you'll see some MAJOR enhancements in this next one once it's all done. The particular NVIDIA hardware on that box has been troublesome for everyone, even Linux, and the particular USB stick shows up as two separate drives in the diagnostics. One USB, the other SCSI. There's a hidden partition (probably to make it easier for Windows to deal with - we've seen quite a few of these recently) and so it's appearing as two drives - we're hoping the problem is solved with new SCSI and USB code in KNOS' upcoming new kernel and that you'll let us know ...
