Is it possible to use an RLL controller with Minix? More specifically, I want to take a 30MB RLL drive I have now and use 20MB of it with Minix. I plan on dividing it up into three filesystems -- /, /usr, and /tmp. The other 10MB I'm going to use with DOS. Does the Minix XT hard disk driver support RLL drives? If the "stock" version doesn't, is there a patch that will make it work? -- Marc Unangst Internet: mju@mudos.ann-arbor.mi.us UUCP : ...!uunet!sharkey!mudos!mju Fidonet : Marc Unangst of 1:120/129.0 BBS : The Starship Enterprise, 1200/2400 bps, +1 313-665-2832 ?

You most definitely may accomplish this, however, you must change the sectors per track from the MFM configuration to whatever is used with your particular RLL controller. This change must be made in both the wini.c and fsck.c. I have been running for quite some time now using RLL (15 Minix and 15 DOS) and have had absolutely no problems. My Minix is even on the second drive (I have 2 RLL drives). >Does the Minix XT hard disk driver support RLL drives? If the "stock" >version doesn't, is there a patch that will make it work? I don't know of any patch, but the modifications are simple. The biggest problem is finding out how many sector per track you are configured for. I don't have my system handy, so I am not sure, but I think that mine is set up for 25 (0x19) sectors per track. Enjoy, -- Brian R. Bainter KA7TXA gatech!kd4nc!trantext!brian or gatech!tomcat!brian

Change the diskparameters in xt_wini.c to the ones you need (26 sectors/track if I remember correctly) and it should work. JaKob Schripsema (sch @oce.nl) Oce Nederland B.V. P.O.
