BOOTING from 2940 card SUCCESS!!! |

Figured I would throw this one out there. Just for kicks, I cloned my jag install to an 18 gig Ultrastar on my 2940 card, using the "helper" disk in XPF, I selected a stock apple drive I still have on the main system bus, booted like a charm! This was too easy....thanks Ryan!!!! I am now running that disk as my primary x disk. I ran XBench on both drives, and my transfer went from 4.5 megs/sec up to 15 megs/sec! Jag definately runs zippier! I am up to 10.2.8 on it, and since it is on a much faster bus, it seems to be faster to me than 10.2.6. I plan on hanging onto the 10.2.6 install on the slow drive for now........ |

I agree that there could be something lost in the translation of scsi cards going from pc to mac, especially with the DMA protocols, but the ATI video cards are fantastic in doing this. My flashed 2940 is OLD, but free. I know I could do MUCH better with a newer scsi card especially since my drives on it are at least 7300 rpm wide, so I could get up to 30 gigs/sec I suspect, but it is a matter of economics. What kills me is the same hardware, for the most part, is always cheaper on the PC side. Now if only I could flash that pesky PC 29160N card I have........ |

that doesn't sound like an ACard Mac card. I get 45-49MB/s on one in my B*W and about 44MB/s on my Beige, using the older (and slower) IBM 120GXP model, which is about 20% slower than the 180GXP. That, or the firmware and card aren't current. I opposed to flashing PC cards. |

The ACARD adapters I use to go into SCSI do not support DMA transfer, getting a tota 17-18 MB/s. The hard drive by itsef will (IBM/Hitachi 120/8MB/7.2k) will pump aboyt 40mbps, and about 32 conected to a oxford firewire. The problem of the ACARD scsi/IDE bridges is that they are limited to the winbond IDE controller max bandwidth. But I'm really happy to go from 5 to 17 MB per second. (8500 g4 800) |

here is the link to cccloner.... http://www.bombich.com/software/ccc.html This is an X native app that can clone your X disk even if you are booted in x. It is small, and I have had great success with it, even cloning an external scsi drive on the db25 connector, and plugging that drive into another machine and running my jag install from that via XPF, just to test....;-). (my spare is an 8500 g3 300 168 megs ram, I ran XPF from the external drive and it worked) There is no terminal line stuff, and is VERY easy. There is a help file with it.... Also, if you use it in conjunction with psynch, a little perl script.. http://search.cpan.org/dist/MacOSX-File/bin/psync It will synch up the files on both drives, saving you tons of time running cccloner. A fresh clone can take 45 minutes, with psynch, less than 10-15. Hope that helps... Jim |

w18593323 "... IBM deskstar 7200 8M buffer 120 GB and an IDE/SCSI adapter I get 17 MB/s. " You should be getting closer to 40MB/s using the 180GXP you have. 17MB/s is what I get on Beige's IDE (ATA/16 bus), and 48MB/s on ACard (non-RAID version). The ability to clone and to read the boot blocks off another drive seems like it helps a real lot. the trick is to have installed OS X already. OWC has some dual channel 3940 cards, too. |

Cnn you describe the procedure with more detail to clone it. I have a 2940 and I've never been able to boot. I have been experimenting under 9 and usen IBM deskstar 7200 8M buffer 120 GB and an IDE/SCSI adapter I get 17 MB/s. IT makes a BIG difference. Thanks BTW, if any one is interested, I have a bunch of adapters at 40/pc |

Oh yeah, I also have a beige g3 with an IDE drive partitioned off into 2 three gig sections, one for 9.2, one for jag. It works well. I cloned the drive to another IDE as a backup, 2 partitions, jag on first 5 gig and 9 on second 5 gigs. It boots 9 fine, but the backup fails to boot X. I am aware of stuff written to a g3 drive on OS install, but I will try this to see if I can get the jag backup to boot using the other partion as a helper. If I can I will post. Jim |

It is running in Ultra mode. the theorectical max on the card is 20 meg/sec, as it is old (circa '95), and I had to flash it from a wintel box, so if I get over 15, I am happy. It won't kick up any further. The 'Cuda is an OLD refurb, but cheap. I have a 10k Cheata on the way, and though I still won't be able to get the max transfer out of it, 10 meg/sec max on that bus, I will replace the VERY old 4 gig 'Cuda on the main bus which just crawls right now, as you know. My ride is a g4 800 w/ 1gig RAM, so that does help offset the slower buses, and so far, this machine has done very well considering what it is. I am still working on converting my 29160N from wintel, which would certainly boost performance, if I can get it to work. I am not sure if I can extract the ROM from the power domain utility yet, but I have all the tools on the wintel side to do it, and am looking through res edit on the mac side to find the location of the ROM file. It does show up in ASP, but so far, it is non-functional. Thanks for the tips on the newer drives. I am saving my pennies for a g5, so trying to stay as current as possible, without spending the $$$$$;-) Jim |

That might help on a Beige G3 where I'd like to boot off an ATTO card and 10K Atlas. Have you checked to make sure your 2940 is running in wide mode? how old is the Seagate (7.2K 'Cuda?) as that sounds too low, more like UltraSCSI bus. The 10K.4 Cheetah from a couple years ago was slow by today's standards but got 33-35MB/s. I like Atlas for their higher sustained reads and work well in older systems. You can pick up current generation 36GB 10K drives (68-pin, too) for ~$160 from www.hypermicro.com and other places. 10K.6, latest Ultrastar or Atlas 10K IV (which is capable of turning in 60's. What doesn't work well, is SATA FirmTek in Vintage pre-Beige G3 systems, ~20MB/s, but easy to use, thin cable and it did work in 7300, just not as well as ATTO PSC which turns in 40MB/s. |
