Re: [Q]IBM's Java 1.4.1 with IBM's JIT
Oh, by the way, the fixed worked on my G3 upgrade
card. Here's my /proc/cpuinfo
cpu : 740/750
clock : 195MHz
revision : 2.2 (pvr 0008 0202)
bogomips : 599.65
machine : Power Macintosh
motherboard : AAPL,7500 MacRISC
detected as : 16 (PowerMac 7500)
pmac flags : 00000000
L2 cache : 256K unified
memory : 640MB
l2cr override : 0xbd080000
pmac-generation : OldWorld
Strangely, it only says my clock in 195Mhz when its
supposed to be at 300MhZ. Oh well, another ppc
problem I got to work out.
