Top stories of Jan. 8th, 2001:

MacOS X Beta Driver for Adaptec 39160 SCSI Card:
Barney Buoy sent a link to download Adaptec PowerDomain 39160 1.0b19 [link expired] driver for OS X beta. Adaptec's Mac OS X drivers page notes this has been tested only with Mac OS X Public Beta and not for use with earlier or later releases of Mac OS X. As noted in the OS X Beta section of the FAQ here, they previously released 29160N drivers for OS X beta. Many of their older cards like the 2940/2940U2W/3940/3944 will not have OS X driver updates however, see their MacOS X Info page for details

2nd Report of Sonnet G3/500 Running at 336MHz in Beige G3:
One of today's entries in the Rate Your CPU Upgrade Database is the 2nd report from a Beige G3 owner that a Sonnet G3/500 ZIF ran at appx 336MHz (not 500Mhz) after a restart. I really wonder if this is some issue with their 'bus sensing' design - which automatically detects the motherboard bus speed and sets the bus/cpu ratio accordingly. I've written my contact at Sonnet for comments on this issue.

Reader Report on EZQuest Firewire CDRW Failure (Bracket Shorted to Ckt Board?):
Although I don't remember any reports like this from EZQuest owners in the Drive Compatibility Database in the past, a reader sent an email reporting an almost immediate failure of his CDRW drive, along with a photo showing a metal bracket across trace paths on the Firewire/IDE bridge board. Click here for Details.

Reminder on Replacement PowerComputing Power Supplies:
A reader wrote that he saw a cost-saving tip on using ATX power supplies in a PowerCenter on a news page from Feb 1998 here. His Powercenter had suddenly died and as suspected, it was the power supply. Generic ATX PC supplies are very cheap (from $25 and up depending on wattage). Some of the best ATX supplies I've seen are made by PC Power & Cooling, but they're more expensive than generic brands.

"hi mike.
just to let you know that i received the ultra-quiet atx "silencer" 235 power supply thursday, installed it and everything works fine now. i'm glad that was what the problem was. i didn't think it was anything else, but you never know. so indeed, you can use the 235 or 275 "silencer" power supply from pcpowercooling in a powercenter 150. i'm quite happy not to have needed to spend a lot of money on a refurbished powercomputing power supply, that i saw going for $299! $65 was pretty good for this one.
thanks again for all the help!...
best future,

Most PowerComputing systems (all that I know of) used ATX supplies, as did some other clones. For other tips on PowerCenter/Pros, see my 1997 Inside the PowerCenter Pro review. (Later pages of the article show views inside the case, identifying components, etc..)

BTW: The Systems page G3 Macs section has articles on Beige and B&W G3 ATX case conversions which include comments on power supplies. (Beige G3 uses ATX compatible, B&W G3 has -5V pin difference).

ATTO Tools 2.5 Feedback - Can't Benchmark Network Drives:
Last Friday's news included a note about updated ATTO SCSI firmware and v2.5 of their Tools utility that many of us use for testing drive performance. A reader writes that v2.5 removed a valuable feature, the ability to test drives on network servers:

" Mike,
The new ATTO ExpressPro-Tools 2.5 no longer detects and shows server mounted volumes. Boo, hiss! A very valuable capability we use to detect 100Mbps Ethernet server volume performance hits. You'll have to stick with v2.3.2 to examine server mounted volumes performance.

Reader Notes Problems w/Yamaha 16/10/40 IDE CDRW in G4:
A reader sent a report on issues he saw with an IDE Yamaha 2100 (lightspeed) 16/10/40 IDE drive in his G4/AGP and swapped into a Yamaha 8824 firewire case. I've added his report to the previous page on Yamaha 2100 CDRW drive feedback.

Why Does a Large Drive Appear as 4GB over my Network?
This question was asked in email over the weekend and in one of today's drive database entries from a 6500 owner that had upgraded to a 20GB drive. The answer is in the Frequently Asked Questions, Networking section. See this Apple TIL on "AppleShare File Sharing: Chart of All Limitations" for an explanation.
