Also, this position disables the keyboard, mouse and floppy disk drive. [ 5 ] The Workgroup Server 95 models include the "Workgroup Server PDS Card", which provides three capabilities: Two SCSI controllers with two internal SCSI connectors (plus one external connector); a DMS SCSI control chip that reduces I/O load on the main CPU; and 128 KB ...
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]
For this reason, 512Ke users' only hard disk option is the slower, floppy-port-based Hard Disk 20, or similar products for the serial port, even though the 512Ke ROMs contain the "SCSI Manager" software that enables the use of faster SCSI hard disks (because the ROMs are the same as the ones used in the Mac Plus, which does have a SCSI port ...
Early BIOS versions did not have passwords or boot-device selection options. The BIOS was hard-coded to boot from the first floppy drive, or, if that failed, the first hard disk. Access control in early AT-class machines was by a physical keylock switch (which was not hard to defeat if the computer case could be opened).
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 ...
This drive replaced the Apple ]['s Shugart drive and the 871K FileWare/"Twiggy" floppy drive used in the original Lisa as the storage medium chosen for the original Macintosh. The single-sided 3.5-inch floppy stored 400 KB by spinning the disk slower when the outer edge was used.
A modern PC is configured to attempt to boot from various devices in a certain order. If a computer is not booting from the device desired, such as the floppy drive, the user may have to enter the BIOS Setup function by pressing a special key when the computer is first turned on (such as Delete, F1, F2, F10 or F12), and then changing the boot order.

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 ...
