Solutions, Tips and Notes

  1. Mike Leavitt shares a friend's experience on why the GVP 4060 won't fit into an Amiga 3000 without modifications: "The size of the board is the problem. It works fine if you hack the drive tray enough to fit it in, but without a hack saw it's a no-go. Specifically, the RAM won't fit (just like the CSPPC from DCE) without cutting a hole in the drive tray. It is no problem in the A3000T, of course. There may also be a conflict with the native SCSI, with an MKIII here, I can only use external devices on the native controller. I wish I had more information on that, but an A4000 owner pointed out that the manual tells you to remove any SCSI controller card you have so the SCSI on the 4060 will work. Removing the SCSI chip would disable the native controller though, and should solve the problem if it becomes one.".
  2. Darren Eveland notes on comp.sys.amiga.misc (August 8, 2000) that the GVP-m '060 and QuickPak cards were apparently designed by the same person (possibly Jeff Boyer?)
  3. Damir Dardagan responds to Hal Greenlee's June 7, 2000 post on comp.sys.amiga.hardware about running a GVP-m 4060 Trex-II in an A4000T: "My GVP-m 4060 Trex-II is happily running in my A4000T (Amiga Technologies/Quikpak model)." Mike Woods notes that the 4060 will not run in a Micronik Z3 board processor slot.
  4. Michael Bourne shares a solution for 2060 users: "The new patchline in DEVS:NSDPatch.cfg (posted below)


    from Boing Bag #1 does wonders for tekscsi2.device where removables are concerned. Writes to Zip drive no longer freeze the bus when the Zip is asleep, and there's an "Unexpected Error" while the Zip gets up to speed. In addition, OS 3.5 provides the ability to boot with the new Fast File System (v45); a normally "foreign" filesystem where the Tekmagics are concerned."
  5. Carlos Mason suggests using the latest version of Setpatch, as this seems to lengthen the time between lock-ups. He also notes that users of ImageFX3 and Aladdin 4D v5.0 may want to avoid the GVP libraries: "As soon as I got Carsten's libraries installed, both at least ran. Aladdin 4D likes to crash every now and then, but then again, that could be because it's not very CyberGraphX aware."
  6. Michael Bourne notes that Ralph Babel did port the GURU ROM to the GVP SCSI using the NCR chip:

    Greg Kimnach asked:
    > is there a guru rom for the tekmagic card?
    Yes, there is. (Actually, it's _two_ ROMs for the TekMagic
    card.) I ported the omniscsi.device to the NCR53xxx (also
    used on the A4091) when I wrote the 68060.library for the
    TekMagic card in '95. Two years ago, GVP-m voiced their
    interest in the NCR/Symbios Guru ROM, but I haven't heard
    from them since, and there simply aren't enough TekMagic
    cards out there to make it a worthwhile product for
    Ossowski's Schatztruhe to sell and support.

    Apparently the tekscsi2.device/gvpscsi2.device is broken like many others and does not support large drives; i.e. it wraps.

  7. Simon N. Goodwin notes: "If there's anything I might help with, let me know. I've written simple but functional code to bang the controller on the 4060 (and Warp Engine and 4091) directly from Amiga Qdos--and used it for DAT and CD access. But alas I had to return the board after the review."
  8. According to Chris Smith of Software Hut, the SCSI controller on the Tekmagic accelerator cards will not work with internal drives.
  9. Sean Courtney notes that the Tekmagic 4060 will NOT work with EDO SIMMs.

Help Requests

Note: if you're able to solve any of these problems, please let me know so I can post the solution here.

  1. Joona I Palaste adds the following to his previous request:

    I still haven't solved my GVP-4060 problem. I thought that maybe my SIMMs could be getting too worn, so I went out and bought a new 32 MB EDO SIMM (double sided). I put this in slot CN1, with the other slots empty, and set jumpers JR5 and JR6 to ON. Result: Only the first 16 MB are recognised. The computer knows there *should* be memory from 0x09000000 to 0x09ffffff, but it finds out there isn't (so it thinks the card was lying to it). I know this because the program KSRemap fails, yet "Avail Flush" reports 16 MB Fast memory. If I set JR6 to OFF, KSRemap succeeds, because it never tries to access the second 16 MB memory. What I wonder is, how does the card recognise *half a SIMM*? Shouldn't it either recognise the whole SIMM or not recognise it at all? Maybe it's because it's EDO? Would getting an FPM SIMM instead solve this problem?

    Joona I Palaste (4060 user) asks for help (original request):

    I recently bought Sean Courtney's GVP 4060 card. While the 68060 processor itself is working fine, I seem to have problems with one of my SIMMs. I have 32MB of FAST RAM, in the form of two 16MB SIMMs (both single-sided, with eight chips). During the installation of the GVP 4060, I accidentally broke one of the plastic "poles" holding the SIMM in place in slot CN2 of the GVP 4060. Now when I try to put the SIMMs in slots CN1 and CN2, only 16MB of FAST RAM is recognised.

    I think the problem is that the SIMM in slot CN2 is not being recognised. This is because I tried removing the SIMM in slot CN2 entirely, and it did not decrease the amount of detected FAST RAM.

    About my GVP setup:

    I have jumper JR5 (4MB or 16MB SIMMs?) set to ON (16MB SIMMs), and jumper JR6 (single-sided or double-sided?) set to OFF (single-sided). The manual of the GVP 4060 mentions the start addresses of the memory blocks as follows:


                         CN1         CN2         CN3         CN4
    JR5 off, JR6 off  0x08000000  0x08400000  0x08800000  0x08c00000
    JR5 off, JR6 on   0x08000000  0x08800000  0x09000000  0x09800000
    JR5 on,  JR6 off  0x08000000  0x09000000  0x0a000000  0x0b000000                                   
    JR5 on,  JR6 on   0x08000000  0x0a000000  0x0c000000  0x0e000000

    As I stated above, my configuration is JR5 on, JR6 off (so it's the third row). SysInfo reports finding 16MB of FAST RAM from 0x08000000 to 0x08ffffff, so I suspect it just finds the SIMM in slot CN1.

    Is the GVP 4060 capable of using SIMMs in non-adjacent slots? For example, if I have one SIMM in CN1, another in CN3, and slots CN2 and CN4 empty, will it work?

    Is there any way I could test the second SIMM, other than replacing the first SIMM with it (which I don't want to do as it may break the first SIMM as well?)

  2. Jean-Frederic Jacquelin (2060 user) is looking for help with installing Linux on his A2060-equipped A2000. If you can help, please contact him.
  3. Dominique Harelle (2060 user) would like to know if there is any way of installing a foreign file system (PFS3) into the RDB of the Tekmagic boards and have the hard drive automount. At the moment he resorts to mount files as the partitions refuse to mount at all unless they are set to use FFS.
  4. Mike Pindzola (2060 user) would like to know if anyone has these problems:

  5. Mike Quinlan (2060 user) has the following problems:
  6. John Robertson (4060 user) would like to use his Umax 1220s scanner with his 4060. He describes the problem: "Michael Bourne and I have tried for many hours trying to get this to work with no success. The problem is that the machine locks up when the GVP board starts talking to the scanner on boot. All terms and cables are well within SCSI specifications. I have heard through Software Hut that Michael at GVP-m has fixed this problem for others but I have not been able to reach him since I bought my card. Is there a magic fix?"
  7. Sean Courtney (4060 user) asks for help: "Chris Smith recommended I put a CPU fan on the 68060 on the Tekmagic board. I went to Radio Shack and found a Pentium fan that's the perfect size, but it has a special clip on it (a Ziff or something) that's not on the Tekmagic board. If a fellow user can tell me where I can find a fan that will easily fit on it, or at least how to hot-glue or otherwise fit the same fan to the chip, I'd really be grateful!"
