- Hello,
-
- Sorry for the size but I figure the more information I
- provide up front the more likely I'll be able to get help
- in solving this vexing problem.
-
- Here's the set up that I've finally put together on my
- Amiga 1000. A Microbotics HardFrame purchased used from
- the internet is installed in the expansion cabinet, no
- problem there. I fashioned a 50-pin SCSI internal to
- external cable to the rear of the expansion cabinet.
- Then a 4-6 foot 50-50 SCSI external cable runs to another
- cabinet with its own power supply and fan that contains a
- Ricoh 5500 50MB removable cartridge drive. It came with
- documentation so I know I've jumpered the device address
- correctly as unit 1. The Ricoh is the only device on the
- adapter and is terminated.
-
- The HardFrame and HardFrame.info files are in the expansion
- directory. It seems I have to have the Ricoh powered on
- in order to boot. If it isn't then after inserting
- Kickstart 1.3 I never get the insert workbench image. I
- can live with this for now. I think I also have to have a
- cartridge inserted but am not sure anymore. Anyway if
- I have power and cartridge I boot just fine. SysInfo
- reports the existance and serial numbers of all three
- cards in the expansion box (8M memory, prototype A2090, and
- the HardFrame).
-
- The formathf command works just fine, reporting the
- presence of the Microbotics Hardframe and the Ricoh 5500
- as unit 001. The drive access light flashes and I can
- hear the arm move as the low level format proceeds. I
- get no errors from this procedure.
-
- Next I try to run rdprep. My objective is to use the
- same filesystem (oldfilesystem) as I use on my two hard
- 42MB MFM Microscience hard drives. I figured if this
- worked I would consider using the newer fastfilesystem.
- The problem is even after answering all of the questions
- presented by rdprep I can't do a cd or dir or mount the
- device. Neither info, assign, nor sysinfo show the SCSI
- Ricoh drive.
-
- In truth some of the questions asked by the rdprep are
- confusing to me. I know all the answers for number of
- cylinders, number of heads, bytes per block etcetera. But
- the stuff on Rigid Disk Blocks vs. Partitions is confusing.
- I want only one partition. I prefer the oldfilesystem
- but will use fastfilesystem if necessary. When it asks
- about how many Rigid Disk Blocks to reserve it suggests
- the same number as I input for blocks per cylinder or track
- which is 37 for the Ricoh 5500. rdprep seems pretty happy
- with the numbers. By the way I'm not trying to auto-boot
- from any hard drive, I'm quite satisfied with Kickstart
- and Workbench floopies.
-
- Rdprep then asks if I want to install a filesystem. This
- is where things get bleak. If I say yes, it provides a
- suggested default value of DOS^@ if I take the default it
- says it can't find it. If I provide l:fastfilesystem as
- input to the prompt rdprep accepts the input but I still
- can't seem to use the Ricoh. I know of no name or file
- in the devs: directory that corresponds to the oldfilesystem.
- If I respond "N" to the prompt for installing a file system
- I skip to the part that asks how I want to partition the disk
- drive. I want one partition so I basically accept all of
- the defaults presented since they are what I would expect
- for a single partition and are similar to what one finds in
- a MountList entry for a hddisk.device. It also asks for a
- device name, and asks for five characters exactly. It's odd
- because it gives a prompt that provides a default that contains
- the exact same DOS^@ value that was in an earlier prompt for a
- file system name. I have tried taking the default value,
- and putting in my own admittedly arbitrary values. Nothing
- seems to change the result of not being able to find the
- device. I'm putting this together at the office and hence
- from memory. I have tried naming this device ff0: scsi:
- DOS^@:, all sorts of things. I even made an entry in the
- devs:MountList as FF0: with HardFrame.device just as I have
- done with my MFM drives using hddisk.device with no luck.
- I have made the MountList entry both oldfilesystem and
- fastfilesystem with no change in results. I have noticed
- that if there is an entry in MountList and you do a
- mount command before doing rdprep you will guru the machine
- every time you run rdprep. In fact rdprep just likes to visit
- the guru a lot.
-
- So basically I need a lot of information/documentation on
- rdprep and/or HardFrame that I currently don't possess. I
- also need to know if I need any other commands/files in
- order to access any device attached to the hardframe.
- What's this business about installing a filesystem? Do I
- need an entry in the devs/MountList file? If so what values
- are required and which if any must match input to rdprep.
-
- I also found that on the HardFrame board there is a 20+ male
- pin connector just next to the 50-pin male SCSI connector.
- What is this for? There is a set of six jumper pins on the
- adapter and a second set of three in another location I
- don't recall their labels offhand. The set of three are all
- open, which is the way they arrived. The set of six has,
- with the 50-pin connector oriented below the jumper pins,
- from left to right, closed, closed, closed, open, open, open.
- It would be nice to know the function of all these jumpers.
- If I recall the machine would not boot until these three
- jumpers were installed. In lieu of documentation I just
- started at the left and kept adding one until the machine
- booted.
-
- Any help/information anyone can provide will be carefully
- applied and the results recorded. If you think it would
- help, I can call you from home while I'm in front of the
- system and walkthrough it step by step, if you just tell me
- when would be a good time for you to participate. Or reply
- with info and pehaps a sample devs:mountlist file and input
- for rdprep.
-
- Thanks in advance,
- Michael Wilson
