From linux-2.6.12.2/drivers/message/i2o/Kconfig : The Intelligent Input/Output (I2O) architecture allows hardware drivers to be split into two parts: an operating system specific module called the OSM and an hardware specific module called the HDM.

This allows for the same HDM driver to be used under different operating systems if the relevant OSM is in place.

This card contains a special I/O processor (IOP), thus allowing high speeds since the CPU does not have to deal with I/O. There's only one I2O scsi driver that is able to handle all I2O scsi cards.

Ah. No wonder I recall thinking i2o sounded very cool wen it was announced many years ago. I just never saw it in use much. Seemed like it almost just vanished after it was announced. Yeah, I guess it was more hype than real stuff. Modern bus master DMA PCI SCSI controllers should be able to get the same performance but unfortunately can't be dealt with a single driver. Now I see CONFIG_I2O=m and CONFIG_I2O_SCSI=m in every 2.6 kernel on Debian that I have around. So at least the kernel has support. Perhaps the installer/initrd system doesn't know about it, or the module got left out of the install system kernel filtering. Do you know the name of the module? i2o_scsi, which probably depends on i2o_core and i2o_bus.

Well if the drivers are the ones in drivers/message/i2o/ then yes the installer does in fact leave all of them out. I recently built a netinst for sarge amd64 that uses 2.6.11-9-amd64 instead of the 2.6.8-11 used currently on the official cd, which a few people have used successfully to install on machines that didn't work with 2.6.8. I could try and add the i2o drivers to it as well and rebuild it with that setup if you would like to try that. As long as the i2o uses the standard /dev/sd* scsi driver devices, I imagine it would actually work. Of course I have no hardware to test that on, but I am willing to spend an hour or so updating my netinst image. The other option is to use another drive/controller while installing, then use the i2o in the full kernel installed to transfer to i2o and switch to booting from that. Len Sorensen Nice stuff. On my mashine the hd's are with i2o on /dev/i2o/hda and so on. By the way, they are scsi-disc. :-) Ryven -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

I wonder if d-i would deal with that, but given I believe it uses devfs still maybe it would still find it. Yuck! Maybe I will try after my vacation instead after I think about it a bit. I was trying to do the cd with a kernel update with the least amount of changes possible (which so far has been very few), Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Well I have now made a test image that you can give a shot if you want which has the 5 i2o_*.ko driver modules included in the scsi-extra-modules udeb for the installer. Perhaps that will work to make it find the i2o controllers. If it doesn't you could try loading the i2o_ modules from the console (vt2) yourself and see if it then finds any discs. As I said I have no such hardware so I can't try it out. Should at least be better than the stock installer that doesn't even have the i2o_* modules at all. http://tinyplanet.ca/~lsorense/amd64/ Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
