MS KB Article Q229085 at
covers the
issue of a missing DMA check box: and it's solution. However:
"This issue can occur if a non-ATAPI driver is controlling the drive. For
example, SCSI drives do not have this check box, and drives attached to
third-party IDE controllers requiring a special miniport (such as the
Promise Ultra Wide 66 with the ULTRA66.MPD driver) also do not work."
>From Promise's support site:
"The "DMA checkbox" that you're referring to will not appear for any HDD
connected to the Ultra66. Since the card's sole purpose in life is to
provide you're computer with an ATA/66 interface, the feature is
automatically, and always, enabled. As long as the Ultra66 BIOS detects the
HDD as "Mode 4", the ATA/66 timing will be used."
Promise also provides a means to test this.

|
| It was supposed to read DMA, not DMS.
|
| Yes, it is usually in the device manager/disk drives. double click on
| the hard drive and a menu will come up. One tab will read "Settings"
| and in the middle will be "options". if DMA is unchecked, check and
| reboot, or vice versa.
|
| I am using Win 95, so it might be somewhat different on other OSs.
|
| If this makes no difference, keep DMA checked. Usually the problem is
| it is unchecked, and should be checked, BTW.
|
| I had the exact problem with my Hp S-20, BTW, and this did fix it.
| However, some installation program (I think it was for my CD burner)
| kept turning it off during software installs and upgrades, and then not
| returning it to checked.
|
| This zig-zagging as you call it, is almost definitely a bottleneck in
| transfer from the scanner.
|
|
| Do you have a lot of other items running off the USB port? What IDE/USB
| chip set are you using on your mainboard? There have been some problems
| with USB and the Via Chip sets (which I also use).

| Oh, this is easy. Along the edge of the film are frame numbers and other
| information. When you can read this correctly (not mirror imaged) you
| are looking through the NON-emulsion side. The other side is the
| emulsion side.
|
| Also, the emulsion side usually has a slight bit of texture on the
| image, it is sticker if you dampen your finger and place it one it (use
| a piece of scrap film for this), and usually is slightly less shiny.
| Also in most cases, the film will tend to curl with the inner side of
| the curl being the emulsion side.

| Best of luck, let me know how things turn out for you.
