A company for which I do some contract programming has an extra Conner 80 MB IDE drive lying around, which they've offered to give me...I currently have a 65 MB RLL drive running with Western Digital's RLL- Floppy controller, so replacing it with the Conner drive is only a 15 MB gain...hardly worth the effort. The question is this: is there any way for me to use *both* drives at once? I don't mind using bizarre device drivers to drive either disk, so....how about it? Does anyone know how to do it? -- Dave Read | readdm@ccwf.cc.utexas.edu | ...in large, friendly UT-Austin Nuclear Physics | read@physics.utexas.edu | letters, were the words Graduate Student (Slave) | read@lampf.lanl.gov | DON'T PANIC !

I would say NO, if you are not running operating system, which would support 2 ST-506 controller (like xenix/386). The problem is BIOS and IRQ/Address. BIOS can not handle 2 ST-506 controller (ATID HD is like 'ST-506 controller + ST-506 harddisk), only 2 harddisk with a controller. I/O addresses and IRQ is second problem. There are specified values for SECOND and PRIMARY controllers, but it doesn't help, if we are running MS-DOS. -- --------------------------------------------------------------- Matti Joutkoski, mattij@yj.data.nokia.fi, tel. + 358-0-5673866. ---------------------------------------------------------------
