Title: What do you make of this, (Hardware Issue?)
Post by: punkyclown on October 24, 2015, 01:14:18 AM
I am running an A1200 With excellerator at 30mhz with 40mhz fpu, 32 megs of fast ram.  I have a CF card running 3.9 and all the boing bags.  I have an exteranl floppy drive. When I was laoding DPaint V the Install aborted after it ask me to insert the next disk, it said the disk was not loaded. So what I had to do was to swap out the next disk before it was called for. So it would be loaded when the software looked for it.  This was not the only program I had this issue with.  Lucklely I had two floppy drives so I could do this.  Anyone else seen this?
Thanks
Brad

#See all the other threads on this forum about random things happening caused by bad floppy drives and disks.  :D

Could be a G-Force Issue if you have one. Anything beyond the limit is ignored.

I have one in my A2000 with max 16Mb, Must remove 4Mb to make all stuff work. Graphics  and audio cards won't work correctly and many errors.

Remove the external floppy and see if it works with just 1 drive. if so it may be a power supply issue.. of course bad caps play a role in so much also.
As mike said, probably a case of bad disks etc.

That makes no sense, Unless:

You are mapping fast ram into zorro2 space that other cards need,in which case this is terrible use of a accelerator and slows everything down and causes the problems you mentioned. set the jumpers to map the ram as 32 bit.

or you have some bad ram that is causing troubles,but i would bet on the above being the trouble.

in anycase this is not a normal thing for a gforce in the a2000.

It's a 030/40 combo max 16 Mb. Add a PIV, remove 4Mb mem. simple.

That's all really interesting, your saying my perfect Amiga A1200 from
1994 has some errors in it, impossible.  I guess I need to check my
board, don't remember what model it is.  But I believe I only have two
16mg modules in there. What's PIV?
Thanks

I know some of the lower-end GVP boards did wacky things with memory, especially some of the early ones.  But this still shouldn't be necessary if the board can map its memory fully into the 32-bit address space.

LOL.  Thread has gotten a bit OT from your original question about your 1200.  PIV is a graphics board:  http://amiga.resource.cx/exp/picasso4

Possible for you to pick up a new floppy drive from AmigaKit for around $22 (http://amigakit.leamancomputing.com/catalog/product_info.php?cPath=28&products_id=294)?  And while you're swapping that in carefully inspect the condition of all your caps.  That's what I'd start with if I were you.  Good luck!  :)
