In System 1, the menu had items related to emptying the Trash, cleaning up the desktop, and disk options. By System 1.1, the menu allowed the user to choose an alternate startup program to be run instead of the Finder at boot time; the feature was replaced in System 7 by the "Startup Items" folder in the System Folder.

GS/OS is an operating system developed by Apple Computer for its Apple IIGS personal computer.It provides facilities for accessing the file system, controlling input/output devices, loading and running program files, and a system allowing programs to handle interrupts and signals.
A file containing such contents is sometimes termed "a BIOS image". A BIOS might be reflashed in order to upgrade to a newer version to fix bugs or provide improved performance or to support newer hardware. Some computers also support updating the BIOS via an update floppy disk or a special partition on the hard drive. [57]
In Mac OS 7.6.1, Apple removed support for writing to MFS volumes “as such writes often resulted in errors or system hangs”, [3] and in Mac OS 8.0 support for MFS volumes was removed altogether. Although macOS (formerly Mac OS X) has no built-in support for MFS, an example VFS plug-in from Apple called MFSLives provides read-only access to ...
Many of these tools were originally designed to boot from a floppy disk drive. The Ultimate Boot CD made it possible to run them on a PC without a floppy drive. [5] UBCD can also run from USB for computers without an optical drive. [5] The UBCD website has relatively good documentation for using the UBCD, and a discussion forum. [6]
The Mac IIx included 0.25 KiB of L1 instruction CPU cache, 0.25 KiB of L1 data cache, a 16 MHz bus (1:1 with CPU speed), and supported up to System 7.5.5. The IIx was the second of three Macintosh models to use this case allowing dual floppy drives and 6 NuBus slots; the last model was the Macintosh IIfx .
It is the earliest Macintosh model that can be used as an AppleShare server and, with a bridge Mac, communicate with modern devices. [3] The Mac 512K originally shipped with Macintosh System 1.1 but was able to run all versions of Mac OS up to System 4.1. It was replaced by the Macintosh 512Ke and the Macintosh Plus. All support for the Mac ...
The drive number (for INT 13H) assigned is any of 80 hex (hard disk emulation), 00 hex (floppy disk emulation) or an arbitrary number if the BIOS should not provide emulation. Emulation is useful for booting older operating systems from a CD, by making it appear to them as if they were booted from a hard or floppy disk.
