- Hi all!
-
- I have a severe problem..... I have just put my trusty A4000 into
- a custom made tower case and Zorro expansion. (Made by GSoft in
- Adelaide) Everything is working fine, including a total of 5 Zorro cards:
-
- EGS Spectrum
- Multiface III
- Quicknet ethernet
- A4091 SCSI 2
- Vlab Composite
-
- However, now the system is only recognising Fast RAM in one megabyte
- blocks. Ie: I have 2 4Mb SIMMs for fast RAM, yet the system is only
- picking this up as a total of 2 Mb. If I remove one of these SIMMs, I
- get only 1 Mb of fast ram... etc etc...
-
- I know there is a jumper on the motherboard that configures or determines
- the appropriate SIMM size. This is definately set correctly (ie: 1 Mb vs
- the 256k setting).
-
- I have checked the pins and they seem OK. I have also replaced thew
- jumper used. There does not appear to be any damage to the pins
- or solder, and no apparent broken tracks etc.
-
- Is there something that I have missed, or can anyone help me out
- otherwise?
-
- cheers,
- Phil Hoffmann.
