Updating a mac g3

The onboard ATA was upgraded to Ultra ATA/33 (in fact an extra UDMA-33 controller was added, see above), but SCSI was no longer present, having been replaced by two Fire Wire ports, a new standard (IEEE1394) running at 400 Mbit/s (50 MB/s) — faster in theory than even the ATA/33 (33 MB/s) hard drive controller.

This both made them easily accessible and improved their cooling by keeping them away from the heat-producing CPU and power supply.

There was room for four internal hard drives and an internal fan was positioned at the side of the case to blow cooling air over them.

Alternatively, the transfer mode can be limited to Multi-Word DMA Mode 2 through the use of third-party driver software such as FWB Hard Disk Toolkit.

The secondary ATA channel has also been reported to have issues with respect to flash upgrading certain DVD burners.

The I/O "Heathrow" had been replaced by "Paddington" (adding 100 Mbit Ethernet and power save features), the audio chip "Screamer" (on the beige G3's "Personality Card") had been replaced by "Burgundy", and other controllers for Firewire (Texas Instruments PCI-Lynx), for USB etc. Though still based on the Power PC G3 architecture, the G3 B&W was a totally new design.

The first new Power Mac model after the release of the i Mac, it used a novel enclosure with the logic board on the folding "door", which swung down onto the desk for easy access (a design that was also used on all Power Mac G4 models except for the Cube), and borrowed the i Mac's blue-and-white color scheme.The Power Macintosh G3 series (commonly known as the "Blue and White G3", or sometimes either as the "B&W G3", "Yosemite G3" or "Smurf Tower" to distinguish it from the original Power Macintosh G3) is a short-lived series of personal computers designed, manufactured and sold by Apple Computer Inc. It was introduced in January 1999, succeeding the original "beige" Power Macintosh G3, with which it shared the name and processor architecture but little else; it was discontinued in favor of the Power Mac G4 line in August 1999.The Blue & White G3 used a modified version of the memory/PCI controller, the Motorola MPC106 (codenamed "Grackle"); it used the MPC106 v4.The logic board had four PCI slots: three 64-bit 33 MHz slots, and one 32-bit 66 MHz slot dedicated for the graphics card, an ATI Rage 128 with 16 MB SGRAM.Four 100 MHz RAM slots accepted PC100 SDRAM modules, allowing the installation of up to 1 GB of RAM with the use of 256 MB DIMMs.The entire right side of the case was a door that hinged down by pulling a recessed latch at the top.
