Gvp a2000 hc+8
« on: December 18, 2012, 12:22:32 AM »
Does anyone have all the jumper settings for one of these boards?  The book doesn't have settings for all of the jumpers.  The card is a rev 2, but is different than the ones pictured on the Amiga Hardware sites.  It has j5, j6, j7, j8, and j9 for RAM.  I have a jumper on j7 and j9 for 0 RAM.  It has J3 and J4, one of which is autoboot, it just says "boot" above those two.  J10, J11, and J12 say "ID" and are all open.  Then there are two toward the middle of the board, and each has 3 pins, they are J2 and J13.  The manual doesn't even mention these.  

Thanks

So, I've tried replacing the autoboot rom with a known working rom, removed all memory and set the jumpers for 0 meg.  Computer will not see the board.  If I hold down both mouse buttons, and look at the boards, it doesn't show up there.  Anyone have any ideas?

Thanks.

Yeah, I've looked at that.  The board I have has a couple of jumpers different.  What happens, is if I use the SCSI controller on my Gforce 030 combo card, any ClassicWB, or OS higher than plain 3.1 (even it is a bit flaky) goes guru when I have any fast memory installed in my A2000 via Zorro II.  There is another thread about this.  I worked with another guy on here, who has the same Gforce card, and he had the same problem, he actually found out that it was the extra memory causing the trouble.  If another SCSI controller, other than the on-board Gforce controller, is used, all is well.  I got the HC+8 off of ebay, with the description saying the computer wouldn't recognize it, so I got it hoping it was a bad autoboot rom or jumper setting.  I have a plain A2000-HC controller, and tried it, and all is well, but transfer drops to 1 mb/sec, as opposed to 2 mb/sec with the Gforce controller.  So unless I get the HC+8 fixed, which may be a lost cause, I am stuck with only the memory on my Gforce, or all of my memory, and a slow transfer from the SCSI controller.

The guy I tested with said that another GVP board would work, using the auto-boot on my Gforce, to get the gvpscsi.device.  I tried that, and it still doesn't see the HC+8, so I'm thinking it is toast.

I am using one of the SCSI multi-card readers as the HD.

Here is a link to the other post:  http://www.amiga.org/forums/showthread.php?t=63319

I also tried using a SupraRAM card instead of the A2058 described in the above link.

Thanks
