I finally got my Supra/Quantum 80 setup going, but I'm not sure if I'm running the Fast File System. The software supplied with the Supra card did most of the work, but it didn't mention the Fast File System specifically (it's version 5.1, I think). Is there an easy way to tell if a partition is FFS? If I don't have it, do I just follow the instructions in the Enhancer manual, or do I need to do something special for the Supra software to be happy? Also, it's not clear from the Enhancer manual how big the Slow File System partition has to be. They give an example of one with the entire workbench on it - why would anyone want to do that? I have a feeling these are stupid questions, but I RTFM, and I'm still in the dark. Phil Stone (phil@eos.arc.nasa.gov | ames!eos!phil)

FastFileSystem partitions have to be mounted via the "MOUNT" command. Check your startup-sequence and mountlist. >Also, it's not clear from the Enhancer manual how big the Slow >File System partition has to be. They give an example of one with >the entire workbench on it - why would anyone want to do that? On my 2nd HD I use a partition of only 136K. On the 1st (boot) HD I use a partition of 1.1M but its only 27% full. My reason for having a large OFS partition is that the 2090A boots my Amiga from it ;-) >I have a feeling these are stupid questions, but I RTFM, and I'm >still in the dark. Hey you know that it took CBM alot of years to get their manuals that way.

In re: how to determine UNAMBIGUOUSLY if one DOES have the FFS in use ... I have a program named "makeML" which regenerates a Mountlist-equivalent file from the in-memory disk info node. Directory listing and sample output shown below. If you notice the last item (DOSType) in the output of makeML, the "...01" indicates FFS is in use for this disk. The hex value "444f5301" == "DOS<1>". If the value was "444f5300", that'd be "DOS<0>" which is the old file system. I have Supra 4x4 SCSI host adapters on all my Amigas; using Supra 5.1/5.3 software with AmigaDOS 1.3. Disks include Maxtors, Quantums, LaPines, Seagates, Miniscribes, etc. The makeML has been in use (by me) for a l-o-n-g time and is reliable and safe; the update in March was for the FFS ... it took me that long (from October) to find enough contiguous free-time to back-up, reformat to FFS, and restore the files on my lab system (over 1GB HD). I'm willing to post the program source ONCE if there's any interest. The flak I received after posting the "purge" program recently indicates to me that people care more for babble than for substance in this newsgroup, so I'd like to know to WHERE the program should be posted (and I don't wanna hear: "where the sun don't shine"! :-) Thad Floryan [ thad@cup.portal.com (OR) ..!sun!portal!cup.portal.com!thad ] ------------------------------ output sample of makeML (recorded using HardCopy): CLI7> ls -l sys:autotest/makem* ----ar-e- 89-03-05 17:27:19 15 7564 makeML ----ar--- 89-03-05 17:26:48 13 6579 makeML.c Dirs:0 Files:2 Blocks:28 Bytes:14143 CLI7> sys:autotest/makeml dh24: /* Table size = 16, sectors/block = 1 * Size of a block = 128 longwords, 512 bytes * Formatted capacity = 53250 blocks, 27264000 bytes, 26625K, 26.0M * Unused defs: secorg = 0, prefac = 0 */ dh24: Device = harddisk.device Unit = 3 Flags = 0 Surfaces = 15 BlocksPerTrack = 25 Reserved = 2 Interleave = 0 LowCyl = 1081 ; HighCyl = 1222 Buffers = 30 BufMemType = 1 /* {2,3} = chip, {0,1} = fast */ MaxTransfer = 65024 Mask = ffffff BootPri = 0 DOSType = 444f5301 #

In the installation/formatting software Supra provides, you have a little series of boxes which choose the file system for you. Choose Fast or new filesystem there (i for get what they call it). Make sure you have FastFileSystem in your L: directory when you execute the SupraMount Command. Supra Stores all the partition info on the boot block. You CANNOT boot directly into the FFS using Supras controller with 1.3 You should if you auto boot at all have one regular File System partition and the rest of the partitions New or Fast File System (whatever they call it). -Roger

Yes. Make a file that's 500 bytes long, and copy it to your partition. Then LIST the file with the BLOCKS option, as in 'LIST DHn:filename BLOCKS'. If it's OFS, it will be 3 nblocks long. If FFS, it will be 2 blocks long. You could also use Sectorama to look at sector 0. OFS will have $444F5300 in the first longword. FFS will have $444F5301 in that spot. >If I don't have it, do I just follow the instructions in the >Enhancer manual, or do I need to do something special for the >Supra software to be happy? Not familiar enough with the Supra to help here. >Also, it's not clear from the Enhancer manual how big the Slow >File System partition has to be. They give an example of one with >the entire workbench on it - why would anyone want to do that? The requirement for an OFS partition is not universal. Some units can boot from an FFS partition. Depends entirely on the manufacturer, and how they did things. If yours requirs the OFS partition, make it 'beig enough'. The reason there is no hard and fast rule is that it all depends on what all needs to be on the boot partition for your setup. Leave enough room for the startup-sequence, system-configuration, and any programs needed before you switch control to a FFS partition. One of my boot partitions (I have three, so that I can still boot when I remove a drive for any reason), is 88K, and has the following directory: c (dir) assign endcli mount newcli run L (dir) FastFileSystem devs (dir) hddisk.device mountlist system-configuration s (dir) hdstart hdstart2 startup-sequence libs (dir) arp.library I don't think the Supra uses the standard MOUNT command, so you may not need MOUNT, devs/mountlist etc. >I have a feeling these are stupid questions, but I RTFM, and I'm >still in the dark.
