-
- I want to run NetBSD on my A3000 (which requires minimum 4MB CONTIGUOUS
- FastRAM) and am trying to figure out the best upgrade path.
-
- I have a 16MHz A3000, 2.04ROM with 2MB ChipRAM and 2MB 16 bit RAM on Zorro.
-
- I haven't used this machine for several years, so I'm *way* out of touch...
-
- Should I:
-
- * Plug in a 25 or 33MHz CPU chip or go for an 040 accelerator?
-
- * Use ZIPS on the motherboard to get up to my 4MB minimum, or add SIMMS
- onto an accelerator card? (I have 4MB of 30 pin SIMMS I can pull out of my
- GVP A2000 SCSI controller). It seems to me that ZIPs are going at a
- premium now and nobody else uses them, so SIMMS maybe a better investment?
- NetBSD will not recognize any uncontiguous memory...period.
-
- It appears that the PPI Mercury board accepts SIMMS, however I don't think
- it has a bonified MMU, which NetBSD absolutely requires. It appears that
- the GVP accelerators used custom SIMMs, so my SIMMs wouldn't work there.
-
- I've spent many hours now trying to sort out the best/most cost effective
- way to go and I'm more confused than when I started. Any nice folks out
- there who can help with advice?
-
- TIA,
