I just got an IOMega parallel port ZIP drive (100 MEG, dismountable) and installed it on my DOS/Windows and OS/2 systems. It wasn't easy on OS/2, but it went OK. I then started to install it on my FreeBSD system. Some information sources (any others?): http://www.torque.net/zip.html {mostly Linux ->} http://www.prism.uvsq.fr/~son/ppa3.html {FreeBSD ->} http://www.prism.uvsq.fr/~son/ppa3.c {the source} This source is a port from Linux, and probably hasn't seen HEAVY use. However, I was willing to take a try. This source describes how it should be incorporated. I modified the MY_MACHINE and files.386 files and started a build. I got a compile error on ppa3.c, and had to replace all int32 with int32_t and all u_int32 with u_int32_t. It built then. First, I found that the parallel port address they'd suggested (0x278) was wrong for me, and I needed 0x378 -- which I got from an old 'dmesg' output for LPR1. Now it works. It identifies my device, and I can read it (I haven't tried writing yet, but I think it'll go). However, I find that it takes a LONG time to do the initial device probes. Since the ppa interface is SCSI-ish, I thought the SCSI_DELAY might change this. I reduced it from its original 15 seconds (it seemed MUCH longer) to 5. On reboot, probing now took about 2 minutes! I changed it back to 15 seconds. I'm stuck until I get a bright idea -- or some suggestions. I'll also be asking the author. --thanks, Nate Melhorn (n_melhor@chelmsford.telebit.com)
