OK, here goes. I basically used the exact same config for zip driver as i had used in 3.4. Juan Segovia helped me tremendously, since we both have the same laptop and both of us have ECP and std bi-directional modes for our parallel port bios settings. NB: no EPP, per se. I was running in straight nibble mode under bi-directional standard mode for my port, and things worked. Then, we figured out (he figured out ;-) how i could get ECP mode working by tinkering with some flags. I had heard that my laptop simply wouldn't work with ECP and zip drives, but this was obviously untrue, because i had used it with windows for quite some time under ECP mode. Once ECP was working, there was an apparent dramatic improvement in speed, esp. when writing to BSD zips, not DOS. I was very happy. Meanwhile, Juan has been running -current on his laptop since sometime last year, and that includes his zip drive. I tried every possible combo of flags imaginable under 4.0. I tried the first set i had used that only gave nibble mode, and the recent settings that game me full ECP mode. I'm running 4.0-build #47 because that's about how many zip flag changes i tried. No dice. The problem is exactly as reported in the PR: ppc0: at port 0x378-0x37f irq 7 at isa0 ppc0: Generic chipset (NIBBLE-only) in COMPATIBLE mode .... vpo0: on ppbus0 vpo0: EPP 1.9 mode vpo0: VP0 error/timeout (5) vpo0: VP0 error/timeout (2) vpo0: VP0 error/timeout (5) vpo0: VP0 error/timeout (2) vpo0: VP0 error/timeout (5) Apparently, Fritz has one chipset, while i have the Matchmaker chipset running in the zip Plus 250 meg model. The vpo error is the same. If anyone needs more info, i'll be happy to provide it. 4.0-stable just a few days old Toshiba Satellite 4010cdt laptop Iomega zip plus drive NO PRINTER jm -- -------------------------------------------- Jonathon McKitrick -- jcm@freebsd-uk.eu.org The spice must flow.... -------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
