<P>
I am trying to use my old HP ScanJet IIp as a network scanner. I have
<BR>
it attached to an old 386/40 using the original HP SCSI card[1]. A
<BR>
lineart scan with scanimage takes over 3 minutes. Is this normal?
<BR>
When I turn on SANE_DEBUG_HP I see a lot of time spent probing the
<BR>
scanner.
<BR>
<P>I tried 'scanimage -d net:erwin:hp:/dev/sga &gt;junk.pbm'on another
<BR>
machine which takes about 5 minutes to do the scan (again a long pause
<BR>
at the start, then a slowish scan) but when the scan is done give an
<BR>
endless stream of 'scanimage: stopping scanner... (sig 13)'. I was
<BR>
able to scan using XSane over the network once, but it was slow and
<BR>
eventually crashed with a 'broken pipe'. Xscanimage crashed with
<BR>
'brokenpipe' during a preview.
<BR>
<P>The machine is a generic 386SX/40 (No FPU) with 20MB RAM and a 30GB HDD
<BR>
(Network MP3 server.) running Debian potato with a 2.2.19 kernel. Sane
<BR>
1.0.4 was built from source. I have no other PCs with SCSI ports (or
<BR>
ISA slots to put the card in) so I can't try on a faster machine.
<BR>
<P>[1] Yes, that card does work with Linux. You have to run the DOS
<BR>
driver (mini400i.sys) to configure the IO port and IRQ before Linux
<BR>
boots. I use a floppy w/ DOS, the driver, loadlin and the kernel on
<BR>
it. Read /usr/src/linux/drivers/scsi/README.g_5380 for configuration
<BR>
info. Give it the ncr_53c400a=1 option when loading.
<BR>
