I looked at the device-specific assembly code in boot blocks for the two drives and it seems that besides the geometry they're pretty similar... I assume, of course, that the binary license doesn't allow me to disassemble or modify the kernel, tho. I also recently solved the disk image dilemma -- I made a utility in Visual Basic that lets you examine, import, and export files on various disk images. The disk-specific parts are in interchangeable ActiveX modules -- right now I only have code for RK06 disk images with Unix 6 or RSTS file systems, but the model is easily expandable to any drive/filesystem combination.

Sender: owner-pups(a)minnie.cs.adfa.edu.au Precedence: bulk Hi - Not likely at all. Completely different controllers - the only similarity between an RL controller and an MSCP (RQDX3 for example) controller lies in their both being Qbus cards and disks are attached to them. The RL is about as smart as a rock - it can't even do spiral reads/writes (even the RK05 could do that), so there's code present to break transfers up into multiple pieces if cylinder and side boundaries are crossed. Also the RL is a "traditional" device in that the driver calculates sector/track/cylinder and stuffs those values into registers. With MSCP you have to build command and response ring buffers, fill in a packet with rather badly documented values, and then poke the controller to go look for its new packet. The geometry calculations are done in the controller not the driver. The only concept of geometry that MSCP drivers have is "how many sectors does the drive have" (and even then that value's only used to pretty print something when the drive is first accessed) - somewhat like SCSI in that aspect. Then too the RD52 is 30MB (sect/trak = 18, tracks/cyl = 7, cyl = 480). The RD53 is ~70mb and the RD54 is ~159mb. It'd be easier to add an MSCP driver to V7 than it would be to try and do binary edits on the RL driver to support non-RL devices. Ick. They're about as different as can be. I think you were lulled into thinking they're similar by the fact that most of the bootblock is "boiler plate" (the filesystem search code to look for /boot). The part that deals with the device is small but quite dissimilar. The bootblock is the least/smallest part of the problem. All the boot- block does is load /boot - and that's where you need a more fullfeatured (but still not as full as the kernel's) driver. Then once there's a standalone driver for a device in /boot then, and only then, does the kernel become involved (at which time a full driver is needed). The A.U. license provides full up source - no need to disassemble anything - that can be modified to whatever extent is desired. That won't solve the problem of getting a MSCP driver into V7 unless one can do the development work using a simulator.
