Thanks for your quick reply, and sorry for bothering you. I know now
the problems we have are different from each other. I quit to checkout
-D 20031228-UTC src, anyway.

I'm sure if you set QuadControl in your IIci, NetBSD-1.6.1 works more
lively on it. Good luck to you on eBay.

I didn't know that before Cameron Kaiser (a member of this list) told me
kindly about the daystar patch for PowerCache '030. I believed that
Control Panels in MacOS are not necessary for NetBSD machines.
     Konnichiwa, Cameron-san :)

After reading this post, I remember I have some benchmarks on IIci
with Daystar PowerCache 50MHz at that time (March 2003).
     Card type=P33, CDEV=Power Central v.2.2/PowerCache

Dhrystone Benchmark, Version 2.1 (Language: C)
Program compiled without 'register' attribute
Number of runs through the benchmark: 100000

NetBSD-1.6 + normal IIci ('030/24.95 MHz)
Microseconds for one run through Dhrystone:    149.1
Dhrystones per Second:                                   6706.9

NetBSD-1.6 + DAYSTAR PowerCache (CDEV OFF)
Microseconds for one run through Dhrystone:    169.3
Dhrystones per Second:                                   5906.7
**Dhrystone-2 resolt is worse than normal IIci.

NetBSD-1.6 + DAYSTAR PowerCache (CDEV ON)
**Freeze in the boot sequence

1.5.2 DAYSTAR Patched kernel
     + DAYSTAR PowerCache (CDEV ON)
Microseconds for one run through Dhrystone:    70.2
Dhrystones per Second:                               14245.0


I tested it on 1.6.1(GENERICSBC) today.
NetBSD-1.6.1 + DAYSTAR PowerCache (CDEV ON)
Boot sequence hang up at:

boot device: sd0
root on sd0a dumps on sd0b
[freeze]

This is same as 1.6. Unfortunately, that 'daystar patch' didn't work
on 1.6. Does anyone know a patch or something for 1.6x to avoid this?

To: Joshua Coombs
I'm sorry for bothering you. These tests are all on IIci, not on SE/30.
Is your SE/30 running with DAYSTAR PowerCache now?

Thanks in advance,
