"Java 1.4.1 Update 1 adds the following enhancements:

Improved Java applet support for Safari and other web browsers that support the Java Internet Plug-In.

Improved drawing correctness and performance.

Changes to Java 1.3.1 that provide support for Oracle11i client applications on Mac OS X.

Improved stability, memory usage, and correctness.
For more details on this update, please visit: http://www.apple.com/java/ "

Like the re-release of Bluetooth 1.2.1 earlier this year, this "update 1" version may fix some past issues with the original release. (As of today (5PM ET) the Apple kbase doc on Java 1.4.1 update does not show any new info some March of 2003.
Past news items on the original Java 1.4.1 update:

• Reader report on Safari/Java 1.4.1 Update Bug
• Reader Tips on Uninstalling Java 1.4.1 Update
• Initial release (March 10th)

If anyone finds that the new release solves a past Java bug, let me know.
(Note: several readers wrote to say this update helped, although one reported a problem with it. I'll post their comments in Tuesday's news page.)

"G5 1.6GHz: Atto UL2D card installed fine and G5 booted up just fine
Warning: Putting in SCSI card lengthened the startup time by 20+ seconds, presumably to search for SCSI drives. I'm still waiting for case to arrive to convert internal drive to external.
Don"

I've seen that much (or more) delay at startup from PCI controller cards (IDE or SCSI) even in older macs. I think it's just the system looking/finding the controller card/drives at boot.
I asked Don if the card was a retail or OEM model and if he could boot from a connected SCSI drive (i.e. cloning the SATA boot disk to thte SCSI drive and then trying to boot from it).

Still no idea why one G5 1.6GHz owner noted motherboard damage (apparently -apple replaced the logic board) after trying an ATTO UL4S card - while another G5 owner said no damage was done (although it hung w/black screen at boot). Here's the comments from the UL4S user that reported damage:

"I have a G5 and yes the ATTO U4LS DOES NOT WORK. I've tried it and it burned one of my G5s. Thank God for Applecare.
I asked for more info and he replied)

Yes, it damaged the logic board, nothing would boot, only the white light above the power button. I didn't notice any physical changes no the board or any where else. I didn't see no smoke or any other indications of burning.
The curious thing is, it did recognized it the first time I booted up the machine, and I was able to use the configuration tools, but after rebooting the machine I got the panic Kernel message. I tried it on the rest of the slots, and the same thing happened, it accepted it at the first boot, and after restarting the machine the panic kernel message. Tried it in all three slots, and then the machine wouldn't boot, not a single effort to boot after that, just the little white light.
Jorge "

Here's a summary of SCSI PCI card reports in G5s to date:

• Adaptec 29160: Reported as bootable using OF mod in G5/1.6GHz
• ATTO UL4S: One report of a black screen/hang at boot, one report of damage. (Both reports from G5 1.6GHz model)
• ATTO UL2D: One report of working in a G5 1.6GHz (I asked if a retail or OEM card and if bootable from SCSI drives)

Remember there's the 3.3V PCI requirement but there can also be other compat. issues such as firmware/openfirmware problems, which is why actual end user reports are often the only true test of compatibility, even for cards that the mfr may list as G5 compatible. The G5 tech info/compatibility page has some accumulated info on PCI card compatibility.

" I have a G5 1.8 Ghz and tried to install the emulation software. Basically what I found was that after Windows 2000 Professional (what I had handy) was copied and the emulation tried to boot the system, it stalled during startup. No movement of the progress bar after at least an hour.

On another note, I tried booting my G5 from my DiskWarrior 3 and Drive 10 1.1.2 disks and both failed. This happened with the "C" key down and when I selected the CDROM in Startup Disk. In all cases the machine booted to the internal hard disk drive.

I'm not that surprised about the CDs - in the past I've had to update my Discwarrior CD to boot from later macs that were released after the CD was made. I'd contact Alsoft and Drive10 to see if they are working on CD updates to address this. I've added Richard's comments to the previous page of Wintel/Boch X86 emulator feedback.

" Processor and Bus Slewing
To lower power consumption, heat generation, and fan noise, the Power Mac G5 computer incorporates an automatic power management technique called bus slewing. Bus slewing is designed to run at high processor and bus speeds and high voltage when the demand on the processor is high, and to run at low processor and bus speeds and low voltage when the demand on the processor is low. Switching between different processor/bus speeds and voltages is achieved by a gradual transition that does not impact system or application performance and operates seamlessly to the user. In slewing, the bus runs at half the speed of the processor.
The ranges of the slewed processor speeds are listed below:

Configuration    Processor range
1.6 GHz    1.3 GHz to 1.6 GHz
1.8 GHz    1.3 GHz to 1.8 GHz
2.0 GHz    1.3 GHz to 2.0 GHz

In addition, the Power Mac G5 computer allows the user to control bus slewing mode. The options for specifying either high, reduced, or automatic processor and bus speeds are located at System Preferences>Energy Saver>Options; then select Automatic, Highest, or Reduced.

If the Power Mac G5 computer detects a system temperature that is too high, due to high ambient temperatures or other factors, it will automatically enter bus slewing mode regardless of the selected setting."

If you submit performance test results, please note if you have the Energy Saver settings set to highest performance. (Just to try and minimize any effect this may have on results.) Thanks.

"mike,
"setenv fcode-debug? true" was exactly what i was looking for on adaptecs support-site, but couldn't find anymore. i know i had it from there a few months ago. and i couldn't remember this by myself. it helped. the machine (G5/1.6GHz w/29160) boots from the SCSI-drive.

(Mike had noted a black screen only when trying to use an ATTO UL4S card in the G5. A later mail from another G5 1.6GHz owner said after he tried that card in his system he had to have it repaired, so I asked Mike if he saw any damage from trying the ATTO card.)
no damage done on the G5 or the PCI-slots from trying the ATTO UL4S hostadapter getting to work.
the loaned G5 is still here because of circumstances beyond my control ;-)
best regards,
mike"
