What is the status of Minix support of SCSI hard drives on PC-compatibles? Does anyone have Minix working with the ST02 controller? I have a Seagate ST296N hard drive, and I'm thinking about acquiring Minix, but won't if the two can't be made to cooperate. -David Hinds dhinds@cb-iris.stanford.edu

His driver does buffering, so it's reasonably fast (up to 500K/sec or so on my system).

There are quite a few of us out here who use scsi drives with the "poor man's" ST-02. (It may not have a Megabyte/sec xfer rate, but its faster than a 1:1 MFM drive!) -Douglas Pokorny (drp@buhub.bradley.edu)

They work fine, but we (ehh... I) were not yet satisfied with performance and package design.. However, the driver DOES exist.

We (Magnus and I) are in the middle of a rewrite, so posting would be a bother ... Thanks.

Kevin, feel free to post the old version. My next version will come in 2-4 weeks if nothing disastres happens. >Please post!

Douglas, the ST-0x is better than you guess. I have got about 1M/s with my driver and a friends hd (a good and great one) on raw device (without the FS). But with FS this will slow down to about 500k/s. MaD
