It so happens that I recently spoke with a tech support guy at Supra, and asked him about it. He said that the supramount command uses the information in the mountlist along with a file called Supra.0 in the devs: directory to mount the drive. All that is in Supra.0 is partioning information for the drive. He said that if one were to examine the information in Supra.0 and use it to build the additional partitions in the mountlist, that one could then just use the normal mount command. I examined this file, and sure enough, it seemed to mostly be low cylinder and high cylinder numbers for the partitions. Then looking at the mountlist information, it appeared obvious how to explicitly define separate partitions for the hard disk using this information. I will try this next time I repartition the disk, and see if it really works this way. I guess they do this because they have a nice utility that you can run at disk configuration time that lets you easily define partitions using gadgets for the number and size of partitions. The mountlist contains only information for the dh0: device. I figure that rather than mucking around with the mountlist when you set up partitions, or making the user do it, they set up this file and let the supramount command to do it "magically". They also say that this set up causes no problems with the new, hard-disk optimized file system which they say they have been testing. Anyway, I am quite happy with the Supra. I run it daisy-chained with a CLtd Amega board and have never had problems (the AMega is inboard of the Supra controller). It's also nice to have a clock-calendar built in (though I have had the date trashed by particularly violent crashes - copper going crazy, weird sounds from the audio, etc.). -- Carlos Smith uucp:...!harvard!umb!ileaf!carlos Bix: carlosmith
