Ghost speed differerent in AMD & Intel
I make extensive use of an OEM version of Norton Ghost 2003 that came
bundled with a mobo, and I've always noticed a huge difference in speeds when I make backups on AMD and Intel machines of comparable configurations : AMD always finishes in a quarter of the time taken by Intel. AMD : Athlon XP 2000+ to 2600+ on Asus A7N266, A7N8X and Biostar M7NCG mobos. Intel : P4 1.9 to 2.8 GHz on Intel motherboards (fewer machines tested) All with 256MB DDR RAM, Seagate 7.2krpm HDD. Given below are times taken. The figures are only approximate as I have not kept accurate records and exact hardware configs varied. However they are not one-off operations - I get these figures repeatedly. Basic Win98SE : AMD 1 minute, Intel 4 mins Win98 + drivers + other software (1GB) : AMD 5 mins, Intel 20 mins Win98 + WinXP + other software (3.4GB) : AMD 9 mins, Intel 35 mins I surface-scanned the HDDs and installed the softwares myself. I always use Ghost in DOS mode by booting from CD so there's no Windows involved. HD space ample and defrag makes no major difference. I can't believe that this is mainly due to the difference in CPU types. I work mostly but not exclusively with AMD computers, and since I'm less familiar with Intel systems, I'll appreciate suggestions as to what I'm doing wrong when using the Intel machines. |

It's got to be something in the disk subsystem, CPU speed shouldn't have any significant effect when ghosting a drive. It sounds like DMA is disabled on the Intel systems and enabled on AMD systems. |

It sounds like DMA is disabled on the Intel systems and enabled on AMD systems. yes, DMA is not working on the systems with the slower times, though it's not really an Intel vs AMD issue, merely what the specific motherboard bios is configured to support... I have AMD boxes that don't support it either. For example. an Asus A7S333 won't, but an A7V333, will. |

That would depend on the BIOS. If I were you I'd just open the BIOS up and poke around. On Linux systems the BIOS settings don't matter because the OS handles the devices directly. Windows does use the BIOS to handle disks so BIOS settings do matter (that's why Linux supports large (137G) drives on old hardware and Windows doesn't). |

May not be visable at all on some bios, might be similar to "busmaster IDE" or *** DMA *** IDE""" something-or-other, the specific label escapes me at the moment but there's only one potential setting, it should be obvious enough if present. |

If you need DMA active at all times you can get it by using a Promise PCI adapter. kony wrote: On Tue, 16 Nov 2004 13:51:40 -0500, General Schvantzkoph wrote: It's got to be something in the disk subsystem, CPU speed shouldn't have any significant effect when ghosting a drive.

I suspected the DMA factor myself but didn't see anything I could set in the BIOS (as I said before, Windoze is not involved). I'll check again first chance I get - I don't have any Intel machine with me ATM. |
