If you LIKE writing MacOS drivers, just hit 'n' now. Get the "Rodime Driver Utility," version 2.03. It's on sumex, and also rascal, I think. It's a formatter, driver installer, partitioner, and so forth for Rodime disks. It was distributed to these archives by Rodime for the benefit of Rodime owners. If you don't think it's "nice" to use it for non-Rodime disks, hit 'n' now. Boot with MacsBug installed, and the new disk connected. Start up the Rodime program. Escape to MacsBug. (I use 6.0, earlier versions may use different register names, etc.) Commands entered to the debugger start with '>' and comments start with ';'. > GT SCANSCSI ; Choose from the SCSI menu, "Scan SCSI bus." ; Debugger breaks at SCANSCSI > MR ; You should now be at UPDATESC+000C > SM A5-10F0+n 1 ; Wherein 'n' is the SCSI address of the new disk, an integer from 0 ; to 6. Substitute "ra5" for "a5" with older MacsBug. > G ; The driver utility program now converses with your disk. During ; this time, it may or may not emit error messages, which it shows using ; a modal dialog box. I got "An error has occurred in InquiryDisk Media ; Verification. Code = 4." I chose to ignore it. I wasn't, however, working ; with a Newbury hard disk, but rather with an Apple disk, for reasons which ; I will reveal later. ; ; If there are not very many error messages, attempt to format and partition ; the disk using the Rodime Driver Utility. ; The Rodime driver seems to know how to set up A/UX partitions. More exciting to me is that the driver can handle multiple "Apple_HFS" partitions at once. I have an Apple HD SC 80, which is a very nice disk, except that there is no way, using Apple software, to set up multiple MacOS-mountable partitions on it. The Rodime software gave me three independent MacOS partitions (could get more) which makes it somewhat easier to deal with a disk this size, with the kind of stuff I have on it. The driver mounts all three as separate disks, which the Finder thinks are mounted on "Rodime SCSI Device." Performance seems the same as with the Apple HD SC Setup driver, which I had been using for lack of anything more interesting. The Rodime program does allow you to specify interleave and other interesting hardware-type junk, as well as allowing more interesting partitioning schemes. Disclaimer: Be reasonable, folks. This procedure is for some poor graduate student (like myself) who somehow gets a SCSI disk which doesn't come with software that does what [s]he wants. Use it on your disk, on your Mac, and you will probably like the results. Install it on 20 of them at your employer's place of business, and the fecal matter will sooner or later hit the air circulation device. Earle Horton
