See also Linux kernel documentation (the Documentation/devices.txt file).Ī BSD/SUN type disklabel can describe 8 partitions, the third of which should be a 'whole disk' partition. For example, /dev/sda1 is the first partition on the first hard disk in The partition is a device name followed by a partition number. In such a case the device name will be /dev/hd* (IDE) Linux kernel to support ATA host controllers and devices) make a difference between IDE and SCSI disks. The old systems without libata (a library used inside the The device is usually /dev/sda, /dev/sdb or so. It understands DOS type partitionįdisk doesn't understand GUID Partition Table (GPT) and it is not designed for large partitions. There mayīe reasons of security, ease of administration and backup, or testing, to use more than the minimum number of partitions.įdisk (in the first form of invocation) is a menu driven program for creation and manipulation of partition tables. boot, to store the kernel image and a few auxiliary files needed at boot time, so as to make sure that this stuff is accessible to the BIOS. For this reason people with large disks often create a third partition, just a few MB large, typically mounted on On Intel compatible hardware, the BIOS that boots the system can often only access Usually one will want a second Linux partition dedicated as swap partition. It can use swap files and/or swap partitions, but the latter are more efficient. Linux needs at least one partition, namely for its root file system. In the BSD world one talks about 'disk slices' and a 'disklabel'. Thisĭivision is described in the partition table found in sector 0 of the disk. There are no known emulators of this platform.Hard disks can be divided into one or more logical disks called partitions. RAM: Up to 2 GB Quad channel PC100 SDRAM (ECC, uses propietary DIMMs). Audio Controller: ? 16-bit, 44.1 KHz (CD-quality) stereo input and output subsystem, MPC-3- and Direct Sound III-compatible, Yamaha S-YXG50 software synthesizer.Graphics: Cobalt Graphics Chipset (UMA, OpenGL 1.x only).Motherboard/Chipset: Fully custom motherboard/chipset design using UMA architecture and ARC firmware, also uses the Intel PIIX4 southbridge for USB (USB 1.1/UHCI), IDE (ATA-33) and other stuff.RAM: Up to 1 GB Quad channel PC100 SDRAM (ECC, uses propietary DIMMs).In Windows 2000 there is one known HAL for this platform: Otherwise its hardware is similar to IBM PC, such as PCI bus. Also it has a firmware that is completely different from a Standard PC BIOS, so a new HAL should be created. SGI 320/540 use a proprietary video adapter based on Cobalt chipset. ReactOS is not ported to ARC-based SGI Visual Workstation series yet.īoth 320 and 540 use Pentium compatible CPUs so they could run ReactOS once it's ported.
