Not what you want probably, but it can be done (using suitable cables/adapters). SCSI negotiates speed and buswidth. An Ultra WIde capable adapter is obviously the way to go if you want to take advantage of your UW drive.. > I have been looking at adapters and am a bit confused.

You could also have SCA, this means everything (including the power) goes over one connector. It would really help if you reveal what kind of drive you have...

I want to add a Quantum 9.1 GB hard drive (Model - VK309100LW). I have not yet bought it, but plan on getting it because of the success I have had with my other Quantum drives. The adapter I have been looking at has "high byte termination." I am currently using an active terminator at one end and the 2940 at the other end. Does it matter where I put the new drive? My guess would be to put the new drive as close to the 2940 as possible. It would then look something like this: 2940 | | |-- Adapter and new 9.1 GB Quantum | |-- 2.1 GB Quantum | |-- 2.1 GB Quantum | |-- Atlas CD-ROM | |-- active terminator At 11:43 PM 6/7/98 +0200, Wilko Bulte wrote: >As thehades wrote... >> I have a Adaptec 2940 narrow host adapter with two hard drives and one >> cd-rom.

Is this the rpm: that is reported by disklabel? Which seems to default to 3600. Also: on the same thing, reported information, the number of actual sectors calculated is different to the total sectors reported? ie: If I use the calculation, I get 5386240 sectors/unit. However, disklabel reports 4110000, and changes the sectors/cylinder from 2630 as reported by scsiformat, to 2048. Which is 'correct' ? if thats the right way of calling it. cheers Bob -- Support Whirled Peas. Business in China?

They answered that the PIILS has a serial EEPROM, and that it's a 93c56. As Daniel Eischen suggested, I "forced" this SEEPROM type in pci/aic7870.c and... bingo!!! Now the SEEPROM is correctly read: ahc0 rev 0 int a irq 9 on pci0:20:0 mapreg[10] type=1 addr=00006400 size=0100. mapreg[14] type=0 addr=f0000000 size=1000. reg20: virtual=0xf50e6000 physical=0xf0000000 size=0x1000 ahc0: Reading SEEPROM...done. low byte termination enabled, high byte termination enabled ahc0: aic7880 Wide Channel, SCSI Id=7, 16/255 SCBs ahc0: Resetting Channel A ahc0: Downloading Sequencer Program...ahc0: 416 instructions downloaded Done ahc0: Probing channel A ahc0 waiting for scsi devices to settle ahc0: target 0 using 16Bit transfers ahc0: target 0 synchronous at 20.0MHz, offset = 0x8 ahc0: target 0 Tagged Queuing Device It works!! And the Ultra SCSI speed is now enabled. Thank you very much!!! Now, should I open a PR about this problem? I think that pci/aic7870.c could be patched. I don't know if CAM has this problem with the SEEPROM type. -- JM ----------------------------------------------------------------------- Jose M.

My machine is a PPro/200, and the Jaz is in it's own controller, aic0. Is this expected ? I know that the aic support is not perfect, as stated in it's sources, but in a dd with large block sizes the machine is almost unusable. Or is it a JAZ "feature" ? The jaz drive was at a 2940 controller at first, by I changed it because heavy usage in the jaz media made the whole system slower. At first I thought that the SCSI bus beeing busy with a non-disconectable device would slow all devices, including the system disks. Maybe I was wrong ? Jonny -- Joao Carlos Mendes Luis M.Sc.
