I'm running XENIX 2.3 with two RLL drives and a DTC 7287 comtroller. Do I need to rebuild the kernel on this machine before I can install the system on a machine running of a WD-1007 ESDI controller?

I installed a WD1007 on asylum without doing any kernel changes. I'm running my WD1007 as my second disk controller, and an RLL controller as my first one, and it works fine. I did, a little later on, install the xnx133 fix, for no particular reason other than that it applied to the WD1007. I never saw any effects I would attribute to its presence or the lack thereof. By the way, if you're using a large disk, > 1024 cylinders, Xenix can access the higher cylinders without you remapping the disk geometry on the controller. This is important, because the largest remapped disk you can have is 512MB (64 sectors/track * 16 heads * 1024 cylinders = 536,870,912) and you can get some 600MB to 1.2 GB ESDI drives. I'm running a 660MB fujitsu drive here. DOS, however, will not be able to get beyond cylinder 1024 because of limitations in its internal device driver interfaces. -- - john romkey Epilogue Technology USENET/UUCP/Internet: romkey@asylum.sf.ca.us FAX: 415 594-1141
