--speed and --backtrack has no meaning for the SE. Get rid of this damn<br>
|
|
crippled SCSI-card shipped with the scanner. I've got an Adaptec 1520 and<br>
|
|
486-machine, a full page scan at 300dpi takes just 3 min. And kill anything<br>
|
|
not absolutely necessary before scanning.<br>
|
|
<p>
|
|
A kernel buffer size > 127 kByte won't help to much, as the scanner itself<br>
|
|
has only 128 kByte and the request size must be limited to 64 kByte<br>
|
|
(buffer management not well implemented in firmware).<br>
