The PIC expects interrupt requests from only one device per line, thus more than one device sending IRQ signals along the same line will generally cause an IRQ conflict that can freeze a computer. For example, if a modem expansion card is added into a system and assigned to IRQ4, which is traditionally assigned to the serial port 1, it will ...
Upon inserting such a disc in the CD drive of a computer running Microsoft Windows, the XCP software would be installed. If CD ripper software (or other software, such as a real-time effects program, that reads digital audio from the disc in the same way as a CD ripper) were to subsequently access the music tracks on the CD, XCP would ...
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.
Some host systems—such as photo kiosks, consumer electronics, and other embedded computing devices—cannot correctly mount U3 "smart drives." The problem may arise because the emulated CD-ROM is the first drive presented to the host system. As such, the device is detected as a CD-ROM drive or not at all.
A further complication is that a device traditionally considered an input device, e.g., card reader, keyboard, may accept control commands to, e.g., select stacker, display keyboard lights, while a device traditionally considered as an output device may provide status data (e.g., low toner, out of paper, paper jam).
Another deliberate violation of the Red Book standard intended to make the CD play only on CD players and not on computers by applying bogus data track onto the disc during manufacturing, which CD players will ignore as non-audio tracks. The system could be disabled by tracing the outer edge of a CD with a felt-tip marker. [3] MediaMax CD3
Drives listed with "Loaded: No" are defaulting to the older, slower Bulk Only Transport (BOT) mode. This may occur if the drive's USB controller, the Mac's USB port, or any attached USB hub doesn't support UASP mode. The Linux kernel has supported UAS since 8 June 2014 when the version 3.15 was released. [18]
For example, to access the files on a CD-ROM, one must tell the operating system "Take the file system from this CD-ROM and make it appear under such-and-such directory." The directory given to the operating system is called the mount point – it might, for example, be /media .
