#High Density Floppy Driv

Hi, I recently installed a Commodore high density floppy drive and ADOS 2.1 in my A3000. The system still has the old low density floppy, too. Can anyone answer these questions?… 1. Which floppy should get the section of ribbon cable with the "twist?" (In case it matters, I'm installing AMAX IV also). 2. Why is only DF0: recognized when I boot? Is there something I must add to the MountList or StartupSequence? 3. Do I *really* still need the old low density drive? I've heard it said that the high density one is "unreliable" on low density disks. 4. Does the Cross-DOS included in WB2.1 allow access to high density MS-DOS formatted disks? If so, is there anything I need to do to make it happen? Thanks in advance for any help!

>>3. Do I *really* still need the old low density drive?

To me, the internal space was far more valuable… I have a second hard drive in there. I've never had a problem reading any disk at all with the HiD floppy, (that means 72&1.4 msdos – mac HiD, mac LD, Ami HiD & LD) and up until last week I had AMAX II+ in there (but that's just been replaced by Emplant).

Hi, Michael, Thanks for responding to question #3 about keeping the LoD floppy drive. I figured out that I needed to change the Berg pin on one of the drives to DF1 and now I can use it, but the high density drive does not want to format a HiD floppy to high density (says it will make it 720K). My *biggest* problem is that I could not find the complete ADOS 2.1 upgrade kit and have disks but no documentation. (I bought, from a mail order place which advertises in an Amiga magazine, a set of 2.1 disks which don't have official looking labels. I could not find a set from Commodore with docs anywhere.) Therefore my questions: how do I tell it to format to high density? How do I tell it to do an Amiga format rather than an MS-DOS format (and vice-versa)? >> I had AMAX II+ in there (but that's just been replaced by Emplant). Any comments on why you went with Emplant rather than upgrading your AMAX? And what do you thing of Emplant? Thanks, Brian

Brian, I think that in order to be able to use the HD drive with HD format you need at least KickStart 2.04 (= v37.175). As you have an A3000, I suspect you might still have a pre-37 KickStart on it (i.e. v36.x), in that case you should try to get your hands on a new KS… BTW… 4) Yes, you can! No, you don't have to do anything special. // Chris coming in from Germany \X/ on AutoPilot 1.071……….

Hi, Christian, I have kickstart 37.175 and Workbench 38.36 (I just installed ADOS 2.1). Should everything happen automatically doing anything special? By the way, how does one find out which numbers (like 37.175) represent which software release (like 2.04)?? (Aside from getting it from Germany 😉 Thanks for help from across "the big pond."

Brian, have a look into your Devs/DOSDrivers drawer. There should be an icon for "Pipe" in it. To use your floppy with MS-DOS format you need a "PCx" as well ("x" being the unit, like in df0:, df1:, etc.). If it's not already there, you will find a "PC0" and a "PC1" in your Storage/DOSDrivers drawer. Just copy the file(s) you need to your Devs/DOSDrivers drawer and double-click on it/them which will mount the respective drives as MS-DOS format. From now on this will be done automatically when booting until you remove the files again from the dir. Apart from that, in your Tools/Commodities drawer, you'll find CrossDOS, which lets you alter the "Text Filtering" and "Text Translation" settings (read your manual what they do respectively – I just left'em like they were…). Sorry, I just had a quick browse though MY manuals and it only says "720KB", so I think you may have to create some modified "Mountlist" entries to cater for the MS-DOS HD format… // Chris coming in from Germany \X/ on AutoPilot 1.071……….

Thanks, Chris, I found the *finally* found the necessary files and put them in the right place to have access to MS-DOS floppies. Thanks for the help. Best regards, Brian

Brian, >>how do I tell it to format to high density?<< You shouldn't have to. If you insert a HiD floppy the system should format it as a HiD disk. Since installing the drive, other than the test I did to see if it would work, I don't think I've ever bothered to format an Amiga floppy disk… everything is either on my hard drive, a tape back up, or gets written to HiDensity MSDOS or MAC disks! Who uses Amiga floppy disks? <ducking> Look in your Devs:Dosdrivers drawer. You should have a driver (and icon) for PC0 which is the dos driver for crossdos. If it's not there, look on your utilities or extras disk. I believe that these have to be installed manually when you do the upgrade to 2.1. I'm not certain though, as I still use 2.04 and the commercial version of CrosDos (v5). >>Any comments on why you went with Emplant rather than upgrading your AMAX?<< Lots. I've been a ReadySoft customer for years… going from A-Max to A-Max II to A-Max II+… I waited patiently for each upgrade. I waited even as the announced release dates came and went. I waited for new features. I waited for online support. While they always answered their phones and eventually addressed any problems I had, it was time consuming and frustrating, often requiring me to write or call several times. Faxes went unanswered. The all of a sudden some company announced that they would have a new Emulator on the market that would not only do MAC in the Amiga, but do it in color. And that their product would multitask. And their product would run emulations other than DOS. Utilities Unlimited seemed to be promising everything under the sun, and more. I couldn't wait to see what they came out with becasue it sounded so implausible. Then they went and did it. The first boards shipped with the usual amount of bugs in the software that can be expected in a new product of this type… but more importantly, users like Jonathan Blackwell started reporting that the Emplant actually worked. And maybe even _more_ importantly, he reported getting software updates on what seems like a weekly basis, directly from UU's BBS. Jim Drew was determined to get this thing right, and do right by his customers. Jim appeared out of nowhere and started personally assisting people in the online community here on CIS, (and elsewhere, which I could live without <g>). That did it. With a product as complex and powerful as this, I wanted the support I deserved when I needed it. I don't know how long ReadySoft was working on support for color, but it sure seemed to me like the possibility of rael competition is what made them finally concede and put their act in to high gear for A-Max IV. It was too late for me… I had already decided that if a company like UU was going to support both the Amiga and their users the way they were, I wanted to be using their products. >>And what do you thin[k] of Emplant?<< I'm astounded by the technology and impressed with both the functionality and support provided by UU… I've only just installed Emplant and I can say that I am incredibly impressed. This board is designed to address the needs of using an Amiga in a world that speaks everything _but_ Amiga. It's felxibility will keep my Amiga useful far longer than any other Amiga specific peripheral I might own. – Michael

Hi, Michael, I have managed to format Amiga low and high density disks now. I've been able to read a low density MS-DOS disk in the high density drive, but a high density one shows up with garbage as file names/dirs. It appears that my MS-DOS compatibilities are coming from Multi-DOS rather than Cross-DOS. (I gave up on Consultron a couple of years ago when MultiDOS came along and CrossDOS was being done for CBM rather than for me.) MultiDOS is not set up to read/write HiD disks (at least the version I have.) I will attempt the manual install as you suggest. Thanks for that input. Regarding ReadySoft, I have called a twice this week asking for information on how to hook up the floppy drives and have not gotten an answer. I understand your loss of confidence as I am beginning to question my decision to go with AMAX IV. The biggest reason I did it was because I didn't want to scrounge around for 256K Mac ROMs…I already had the 128Ks. Thanks for the detailed information on Emplant and the customer support. I wish them great success. Best regards, Brian

Hi again Michael, I *finally* found the files you mentioned. I put both PC0 and PC1 into the proper drawer and both floppies (LoD & HiD) worked after a reboot. Thanks loads for the help. Now for one last question (today anyway): Since I installed the AMAX IV and ADOS 2.1 my power and hard drive LEDs have stopped working (the ones on the front of the A3000). Any idea why and what I can do to get them back? Best regards, Brian

Brian, looks like a "pulled plug from socket – will not work" situation. I don't know about the A3000, but in my A2000 the LED's wires lead to some pins on the motherboard (power) or hard drive (HD) respectively, so you might have just pulled them whilst fitting your new boards… // Chris coming in from Germany \X/ on AutoPilot 1.071……….

Hi, again, Chris, >> looks like a "pulled plug from socket – will not work" situation.<< I'm a "hardware" guy and that's the first thing I checked. However, I'll look again next time I open the case. Brian
#140763From: Roy NashApr 25, 1994 5:58 PM
Check to see if the plug has been inverted. As the LED is a Diode it will only work one way. Did this several times myself. Roy

>> Check to see if the plug has been inverted. << I don't believe the LEDs were ever disconnected, but I'll double check. Thanks. Brian
#140174From: New Horizons SoftwareApr 22, 1994 8:19 AM
Brian, Check the wire lead that connects the LED to the motherboard and make sure that is secure. I have also had one machine that had a cold solder joint on one of the LED connections that came free after several cycles of opening up the machine to add cards.

You have to have the HiD floppy as DF0… (There is a patch to use it as DF1, but I'd suggest moving the drive to DF0 anyway.) As to your third question, I've never had any trouble reading and writing low density diskettes with my HiD drive. (PC's have this problem, not Amiga's) Bob Comer — Cruising the nets on Autopilot!

Hi, Bob, Thanks for the help. I'll move the HiD to DF0. Brian
