Getting an Adaptec 2940UW properly working under O |

Machine: PM 9500, 512mb ram, XLR8 MachCarrier G4-400 upgrade, 4x Apple scsi cdrom, 2 Quantum Viking II 9gb Wide hd's and a 2940UW from a PC flashed with the apple firmware (version 4.1). Oh yeah, floppy also. :) Problem: Installed and upgraded to OS9.2.2 while using the 2940UW, no problems at all. OSX will not boot or install unless I am using the slower of the two internal scsi chains (the one facing the edge of the board at top is blown). When ever I try to boot OSX I get several Open Firmware messages about not being able to open the path to the pci slot that the scsi card is sitting in. Solution:? |

Been out for a while... I don't know about a conflict with the Trio. My 3940UW has just worked (except no booting from it). But I don't have any ATA in the machine. I just remembered one problem I had with it under OS X - I had to have something on both channels, or it would die during boot - overly sensitive to termination I think it was. That may have gone away in Jaguar, but I can't be sure. I've always had both channels connected. The secret to getting the ATTO UL2D working is the right level of firmware - at least on the G3's. The 1.6.6 will work fine under OS X. However, under OS 9 I had crashes on boot (the conflict with Foreign File Access) when Finder starts. If 1.6.6 doesn't work for you, if you back off to 1.5, it should work. I got 1.5 from ATTO tech support. I tried 1.6.2, 1.6.3, and 1.6.6. None of the 1.6x versions worked under OS 9. Only 1.5. 1.5 also seems to work just fine in OS X. From what the tech support guy told me, 1.6.x fixes problems with the G4's so maybe you'll have better luck with it. I updated the UL2D on OS 9 with the Mac flasher. There was no problem overwriting Apple's firmware. As an FYI, here's a table ATTO sent me on deep sleep: Power Management Support ____________________________________________________________________________ PSC DC UL2S UL2S UL2D UL3S UL3D FibreChannel OS 9.x NO NO NO NO YES YES YES NO OS X No No NO NO NO YES YES NO |

I seem to recall something about the Trio using too much NVRAM because of the 3 functions it performs. It leaves little room for other devices to use the NVRAM. It should work alone, but when you add other cards in you run out of NVRAM. I believe there is a way to use aliases in NVRAM to cut down on the usage, but I'm not sure if that would fix the problem with the Trio. I belive XPF 3.0, if not 2.2.5, can use these aliases in NVRAM, which could possibly help. |

wesp2, Man would I like to talk to you! Your post covers all the equipment I have and yet I can't get mine to do any of the things you state. Of course, part of the problem may be my Sonnet Trio which seems to create more problems for the ATTO. My old trusty 3940UW works great w/ the Trio but will not allow me to install OSX when in the machine. I might yank it, install X and then put it back in but I think I tried that already and it won't let OSX boot, even from my internal bus where it usually works great. Wish I could just create a reliable dual boot OS9 and X set-up. For DV video the UW speed would even be acceptable. I also have an Apple OEM UL2D and UL3D, neither which work in both OS's, but may try the Windows PC flash to over ride the Apple OEM firmware to the latest ATTO firmware 1.6.6 where evything is supposed to work. Getting legacy Mac's to work in OSX workstations with a full complement of PCI cards is not for the faint hearted! But time is valuable and I'm about ready to throw in the towel and stick with OS9! PM9600 w/ Sonnet G4/800, 1.5 G RAM, Korg 1212, ATI Nexus 128 & Exclaim Rage Pro, Sonnet TRIO (USB/FW/ATA), dual Applevision 20" 850 monitors. Send me your address if you have the time to help me.

Until recently I had been using a 3940UW (dual channel version of the 2940UW) flawlessly on my 8500/G3 since OS X Public Beta. The 2940/3940 are supported natively in OS X by the 78x driver from Apple, although that support is not advertised. The only drawback is that it isn't bootable. So, I was relegated to booting from the 10MB/sec (Fast narrow) motherboard bus and using the drives on the 3940 as secondary drives. It sounds like XPostFacto V3 might make this configuration bootable. Recently I replaced the 3940UW with an ATTO UL2D from OWC. They were selling these OEM pulls cheap - not sure if they still have them. I flashed it with ATTO firmware. The current firmware crashes under OS 9 (version 6?) - a conflict with Foreign File Access I think it was. I backed off to the previous major version (5.x?) and now, along with XPostFacto 2.5.5, have a bootable dual channel Ultra 2 controller running speedy drives on my 8500. No more 10MB/sec disks. I also have an ATTO/Apple PSC OEM from OWC which I flashed with ATTO firmware, and is bootable. I put that in my new Dual MDD. ATTO claims "Full support for the G4". Unfortunately, "Full support" doesn't include power management (i.e. deep sleep), so now my MDD won't go to sleep. Only their Ultra 3 controllers support deep sleep. $$$. Ugh. |

I thought the 2940's were not supported by OS X at all. I have the 29160N and it works great. It has worked for me since 10.1.3. I don't think you can even use it for a secondary drive. I keep hoping the cost will drop so I can get another one for a Beige G3 my wife uses, but no luck so far. Even the ones on Ebay are expensive. Seems like OWC has some of the cheaper ATTO cards... |

I don't think so. This card may work as a secondary drive connector, but as far as I know will not boot. I tried for a while back in OSX 10.0 days, it would always pause for a few seconds and then go back to the OS9 boot screen. I have it my server system (8500/150) hooked to an 18G wide drive for data. Good Luck, Marty PS ATTO Express PCI PSC is the most reliable wide card for the $'s |
