I am currently running sco unix on an intel 486 box with one esdi hard
disk controler and two hard disks. Is it possible to add another hard
disk controler and more disk with out having to go to scsi?
Thanks in advance Andy

Look into your release notes or into the script /usr/lib/mkdev/hd ;-) You can't add a 2nd ESDI or ST-506 - controler. You can simply try it with 'mkdev hd'. -- Karl-Peter Huestegge karl@robot.in-berlin.de Berlin Friedenau Bus: 2,25,48,81,85 U-Net: Bhf.F.Wilh.Pl. ..unido!fub!geminix!robot!karl

YES, but you need a new disk controller card, Perceptive Solutions, Dallas Texas, 214-954-1774 Will allow you to connect an impressive array of different types of disks including many scsi disks.

This is not correct. SCO Xenix 2.3, SCO Open Desktop, and SCO UNIX 3.2 all support up to 2 ST-506 style controllers in a single machine, each with up to two disks per controller, for a total of 4 ST-506 disks. (This includes controllers such as the WD1007 which present an ST-506 interface to the bus, even though they are ESDI controllers.) In addition, SCO UNIX allows you to have up to 4 SCSI disks on up to 2 SCSI controllers, while SCO Xenix 2.3 GT allows you to have up to 14 SCSI disks on 2 Adaptec SCSI controllers. Of course, you have to alter the NDISK and NMOUNT parameters to allow for this many disks on your system. The specific disk you are adding is specified by options to 'mkdev hd'. Only if you are using an SMS OMTI controller are you limited to 2 disks per system. } }-- }Karl-Peter Huestegge karl@robot.in-berlin.de }Berlin Friedenau Bus: 2,25,48,81,85 }U-Net: Bhf.F.Wilh.Pl. ..unido!fub!geminix!robot!karl I hope that this has been helpful. - Paul Zola Software Support Engineer paulz@sco.COM Gotta tend the earth if you want a rose. - Emily Saliers DISCLAIMER: I speak for myself, and not for SCO.
