The ROM and Mac OS operating system released with the new Power Mac machines included an Mac 68K emulator to enable programs written for Motorola 68k series CPUs, including nearly all prior Mac software, to run without changes.

Simply taking off the top cover of the ZX80 and prying the old ROM from its socket and carefully inserting the new ROM and adding the keyboard overlay, the ZX80 would now function almost identically to the proper ZX81-except for SLOW mode, due to the differences in hardware between the two models.

The same technique was also used to page between the new 16 kB editor ROM and the original 16 kB BASIC ROM at the bottom of the address space.

The Stinger-RMP is so-called because of its ability to load a new set of software via ROM chip inserted in the grip at the depot.

More importantly, HFS was hard-coded into new Plus ' 128K ROM, freeing not only space from the system software disk, but also RAM.

A new ROM diagnostic routine could be invoked to test the motherboard for faults and its main bank of memory.

It had 128 KB of ROM on the motherboard, which was double the amount of ROM that was in previous Macs ; the new System software and ROMs included routines to support SCSI, the new 800 KB floppy drive, and the Hierarchical File System ( HFS ), which used a true directory structure on disks ( as opposed to the earlier MFS, Macintosh File System in which all files were stored in a single directory, with one level of pseudo-folders overlaid on them ).

The ZGRASS unit sat under the Astrocade and turned it into a " real " computer, including a full keyboard, a math co-processor ( FPU ), 32k of RAM, and a new 32k ROM containing the GRASS programming language ( sometimes referred to as GRAFIX on this machine ).

* a completely new, 32-bit clean ROM with built-in 32-bit QuickDraw that consists of 2 parts: one part that is the same across all Macs, and another area ( called the overpatch area ) that is specific to each Mac.

In August 1987, Apple released an updated ROM that was included in all new machines and was made available as a free upgrade to all existing owners.

The main feature of the new ROM was the presence of the System 2. x toolsets and several bug fixes.

This update also allowed up to 8 MB for the RAM Disk, added some new features for programmers, and reported the ROM version and copyright information on the startup splash screen.

This update introduced both a new motherboard and a new ROM firmware update ; however, neither was offered to existing owners — even as an upgrade option ( the new ROM, being larger, was incompatible with the original motherboard ).

Some companies use firmware updates to add new playable file formats ( encodings ); iriver added the Vorbis format this way, for instance.

Sometimes third parties create an unofficial new or modified version of firmware to provide new features or to unlock hidden functionality.

Most mobile phones can be unlocked to work with any GSM, such as O < sub > 2 </ sub > or Orange ( in the UK ), but the phone may still display the original branding and may not support features of the new carrier ; besides the locking, phones may also have firmware installed on them which is specific to the network provider.

The advantage of software upgradeability was diminished when many newer hardware modems gained the ability to upgrade firmware to support new standards.

As the firmware only worked in this motherboard and no new firmware updates were ever issued, users commonly referred to this version of the Apple IIGS as the " ROM 3 ".

The new firmware also had an autostart feature which would automatically find a disk controller and boot from it when the system was powered up — earning it the name Autostart ROM.

The new ROM firmware allowed Applesoft BASIC to recognize lowercase characters and work better with an 80-column display, and fixed several bugs from the IIe ROM.

The new firmware removed the code for the cancelled AppleTalk networking device and replaced it with support for memory cards.

In January 1988, a new ROM firmware update was issued to address bugs in the new memory expandable IIc.

The 49G incorporated many of the most powerful interface and mathematics tools available on the HP-48 series into the firmware of the new 49G, including the ability to easily decompile and compile both SysRPL and Saturn assembly code on the unit.

Version 4. x cards are fully backward compatible with existing readers but require updated hardware / software to use their new capabilities ; even though the four-bit-wide bus and high-speed modes of operation are deliberately electrically compatible with SD, the initialization protocol is different, so firmware / software updates are required to support these features in an SD reader.

The Microdata implementations ran in firmware, so each upgrade had to be accompanied by a new configuration chip.

Applying patches to firmware poses special challenges: re-embedding typically small code sets on hardware devices often involves the provision of totally new program code, rather than simply of differences from the previous version.

# Flashing the firmware is cheaper than purchasing a new P910.

Another more advanced method is to attach a TTL to the modem's RS-232 adapter, and get access to the modem's console directly to make it download new firmware, which can then be configured via a simple web interface.

In January 2007, a full port to the new Lego Mindstorms NXT was released as a firmware replacement.

These firmware upgrades added several new features, most notably the ability to adjust or remove the original 25 picture limit, along with various other changes and improvements.

OTA is similar to firmware distribution methods used by other mass-produced consumer electronics, such as cable modems, which use TFTP as a way to remotely receive new programming, thus reducing the amount of time spent by both the owner and the user of the device on maintenance.

Her face was very thin, and burned by the sun until much of the skin was dead and peeling, the new skin under it red and angry.

His advice, his voice saying his poems, the fact that he had not so much as touched her -- on the contrary, he had put his head back and she had stroked his hair -- this was all new.

School began in August, the hottest part of the year, and for the first few days Miss Langford was very lenient with the children, letting them play a lot and the new ones sort of get acquainted with one another.

Satisfied at last, and after a few amorous gambits on her part which convinced Delphine that Dandy was capable of learning new arts, she opened the window and called to her liveried driver.
