" The 10.1.5 update does fix Radeon 7000 problem with the beige Macs. My last post appears on your Radeon 7000 page.
Tom D. "

As I was posting this I received another mail from a Beige G3/7000 card owner that also noted 10.1.5 was working where past versions didn't. (OS X 10.1.4 and earlier also had the same problem with the dual head 7000 card in pre-G3 Macs, and I later had reports were also solved by the 10.1.5 update. **However** all reports indicate there's an corrupted display issue with wake from sleep with the 7000 card and OS X 10.1.5. )

"Update 10.1.5 delivers enhancements which improve the reliability of Mac OS X applications, delivers improved networking, security, support for PC Card serial communication devices, and expanded peripheral device support. Specific improvements include:

Peripheral Device Support:
- Expanded support for new Canon digital cameras.
- Improved support for Nikon FireWire cameras.
- Expanded support for SmartDisk, EZQuest, and LaCie disc recording devices.

- Internet Connect and AirPort applications updated with Chinese and Korean localized content. "

"A concise history of the eMac
Apple designed the eMac after talking to teachers and students about what they most wanted in a computer - features and attributes like a PowerPC G4 processor, a 17-inch flat CRT display, an all-in-one design, and lots of useful applications - at an affordable price. And then something happened. The Apple switchboard lit up like a Christmas tree. The phones started ringing. And ringing. Then came a blizzard of email. All from people of all ages demanding to know when they could buy an eMac for their home. Well, weÌre pleased to announce that the answer is Ïnow.Ó

Note: Another reader wrote that currently the Combo DVD/CDRW drive option is only available to EDU buyers.

" Hello,
The new iBook can be overclocked in software. There are two PLL (clock multipliers). The register HID1 is used to configure them and to switch between them.

I have, with success, changed the clock to 800 MHz. I have installed the CHUD tools from Apple and done the following operations.

1 launch the Reggie application (/Developer/Applications/Reggie)
2. select the HID1 register
3. deselect the bit 15 (if it was yet disabled jump to step 6)
4. click Apply (we select PLL0 as source)
5. select the HID1 register
6. set the bit 24 and clear the bits 25, 26, 27, 28, 29 and 30
7. click Apply (we configure PLL1 to 8x, so 800 MHz)
8. select the HID1 register
9. select the bit 15
10. click Apply (we select PLL1 as source and now we should run to 800 MHz)

Only 800 MHz worked on my ibook. But also, I didn't have the right documentation.
Regards,
Donatello

(I wrote to ask if the speed is reset after a restart (I suspected so)-Mike)

Yes, it resets to 700 MHz. It will be very easy to do a kext that sets the hid1 register during the boot. Currently, I don't have my ibook to try it.

I would like to make a correction.
Step 6, set the bit 24 and clear the bits 25, 26, 27, 28, 29 and 30
[I corrected this in the original remarks above-Mike]
Else I have two remarks:
- the new iBook use a version 1.2 of the 750FX. The fully featured 750FX, able to reach 1GHz, are the 2.0.
- Reggie lets the user enter any value. So it could be dangerous for the iBook because the maximum frequency allowed is 2GHz.
Regards,
Donatello. "

Yesterday's news page had a story with specs/features of the IBM 750FX CPU.
(Note: As with any overclocking, this of course voids the warranty, may not be reliable, etc. etc. - all mods like this are done at your own risk. )
I checked the IBM 750FX specs file linked in yesterday's news and found the following reference. (Some thought the above was a hoax - I don't have an iBook 2002 to try but here's a clip from the 750FX specs)

" (Page 13 under "features" section in power section notes)
"dual PLLs for seamless frequency switching"

(Page 16, para 3.2 Power notes [bold emphasis mine])
"...includes two PLLs allowing the processor clock frequency to be changed "on-the-fly" to match processing requirements.

During reset PLL0 is selected to provide the internal processor (i.e core) clock. The external clock to core clock multiplier is selected using external pins. Thereafter, PLL0 and PLL1 may be controlled using software . The HID1 register contains fields that specify the frequency range of each PLL, the clock multiplier for each PLL, external or internal control of PLL0 and a bit to choose which PLL is selected as the source of the processor clock at any given time."

This sounds like more flexibility than the usual (power saving) clock speed reduction features of many other CPUs.
Note: The question has been raised about the iBooks power saving features conflicting with this hack (perhaps even if all Energy Saver options such as reducing processor speed, etc. are disabled).

"I have an iBook 600 (one of the new ones), and tried the reggie app. First of all, this does work - I don't have an app that checks the CPU speed in X (the only one I found on the net didn't work and others don't work in classic), but I used distributed.net's client to check "speed."

Bits 1, 2 and 3 (note: it starts at 0) seem to indicate CPU speed (or identify the machine). 1 and 2 are checked for the 600, and 1,2 and 3 are checked for the 700. These are not changeable. After hitting "apply", the value return to their default settings.

According to the original poster, bit 15 changes CPU speed based on whether "reduce processor performance" is selected in the energy control panel and adjusts the speed according to bits 24-30. These must set more than just the multiplier - possibly the bus speed, cache speed or other values - 7 bits (128 values) shouldn't be needed for just bus speed multiplier.

Both the 600 and 700 have 25 and 29 checked to set the CPU speed to 400 when "reducing processor performance." Checking all (25-28), (25-29) or (25-30) seem to change CPU speed to 750. Likewise both (25-27), (25-27 and 29) and (25-27, 29 and 30) seem to change it to 700. Bits 29 and 30 are either redundant, affect nothing or set some other parameter. Again these values are from benchmarks compared to the default 600 MHz. I'm not willing to play around more since as Donatello noted, some combination could set the CPU to 2 GHz.

"Hello, I noticed some macsites are mentioning external firewirecases in japan, that do support the faster FireWire, 1394B.

I presume thats because Oxford Semiconductor have released their 922 chip, based on their previous 911 design. It supports both FireWire at 800 Mbit/s, or lower, and USB 2.0. They have an pressrelease at this URL:

[ He later sent links to some 1394B products]
Macpower 1394B/USB 2.0 Enclosures
Seems Computex have one big 1394 area, wish I was in Taiwan, so one could see if more products based on Oxfords 922 was released there.
(also find this: http://www.advanceddigitalvision.com/Arvoo.htm#1394-2-F)
(that last page notes "Supports Multi-Mode Fiber only") "

Granted many devices (single drives) are not really limited by the current 400Mbit/sec FW interface (i.e. CDRWs, portable HDs and even most desktop single IDE drives don't sustain more than that rate - but in many cases the max spec of 400Mb/sec (50MB/sec) isn't being delivered either.)

"Hello, we are a Apple-Dealer in Berlin, Germany.

A few months ago we sold this display to an customer of us.
Unfortunatly this display never will make an resolution of 1900x1200 on the DVI-Port, only 1600x1200...
Neither PC or Mac...
Only with the analog interface (VGA) can you get the higher resololution. You don¥t find any information about that, until you read the manual which came with display...!
We had to send it back, because our customer need this higher resolution too.
Very, very disappointed about the information-policy of Samsung...
Hope I could help you...
Best regards

(All Mac and PC DVI port card specs I've seen show a max DVI res. of 1600x1200 - although Apple lists some of these cards as 23" Cinema (1920x1200 display) compatible with their DVI->ADC adapter - I assume that's still limited to 1600x1200 mode due to the card.)
The only card that I'm not sure of is the OEM GeForce4Ti card - I wonder if that card's DVI port can drive higher resolutions than 16x12.
The other option with an ADC port card would be to use a ADC to DVI adapter ($39 or so - but ADC ports are only on the OEM Mac graphics cards, not on any retail cards.)
