Can use Physical Address Extension to create a virtual disk in memory normally inaccessible to 32-bit versions of Microsoft Windows (both memory above the 4 GB point, and memory in the PCI hole). [13] There is also an open source plugin that replaces the RAM drive on Bart's PE Builder with one based on Gavotte's rramdisk.sys. [14]
Mac OS X users can use the hdid, newfs (or newfs hfs) and mount utilities to create, format and mount a RAM drive. A RAM drive innovation introduced in 1986 but made generally available in 1987 [3] [4] by Perry Kivolowitz for AmigaOS was the ability of the RAM drive to survive most crashes and reboots. Called the ASDG Recoverable Ram Disk, the ...
Protected memory was only added to Macintosh computers with the release of the Mac OS X operating system. According to Andy Hertzfeld, the Macintosh used for the introduction demo on January 24, 1984, was a prototype with 512k RAM, even though the first model offered for sale implemented just 128k of non-expandable memory. This prototype was ...
There are a number of other companies (AMD, Microchip, Altera, etc.) making specialized chipsets as part of other ICs, and they are not often found in PC hardware (laptop, desktop or server). There are also a number of now defunct companies (like 3com, DEC, SGI) that produced network related chipsets for us in general computers.
Software crackers usually did not benefit materially from their actions and their motivation was the challenge itself of removing the protection. [2] Some low skilled hobbyists would take already cracked software and edit various unencrypted strings of text in it to change messages a game would tell a game player, often something considered vulgar.

The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
The maximum random access memory (RAM) installed in any computer system is limited by hardware, software and economic factors. The hardware may have a limited number of address bus bits, limited by the processor package or design of the system. Some of the address space may be shared between RAM, peripherals, and read-only memory.
