lg cd-rw recorder & dvd rom reader

Pikkasen jäi nyt ittelle epäselväksi onko sulla
erilliset laitteet vai yhdistelmälaite - ns.
combo-asema - jota yrität asentaa jo olemassa
olevan romputtimen lisäksi?
Ainakin omassa uudessa koneessa Lg:n DVD-asema
(malli DRD-8160B) toimii hienosti - mitä nyt ei
lue aivan kaikkia huonolaatuisia romppuja! (Komp.
kaikille-lehden mukana tulevia)
- En oo vielä saanu hommattua polttavaa asemaa
tähän kon. joten DVD ja Kiintolevy ovat omissa
IDE-kaapeleissaan Mastereina.
- Tässä onkin pieni probleema, kun emolevyissä on
yleensä vain kaksi IDE liitäntää ja ns. ykkös-
liittimeen ei kannattas laittaa romppuasemaa
kiintolevyä hidastamaan ja toisaalta monet
polttavat ei taas pelitä, jos samaan kaapeliin on
laitettu tavallinen romputin (tai DVD-asema)
orjaksi. (polttavahan täytyy yleensä asentaa
Masteriksi)

LG tekee loistavia näyttöjä. LG575 TFT näyttö
pesee tuplasti kalliimmat sonyt yms. Kyllä LG:n
tuotteet ovat sieltä laadukkaammasta päästä.

The LSI Logic Storage Device Management System (SDMS) is a complete software
package that solves the increasingly complex problem of managing system
I/O. It seamlessly addresses hardware and software interfaces by supporting
LSI Logic's family of SCSI processors and controllers, and a wide range of
SCSI peripheral devices, while offering interoperability across application
programs, operating systems, and host platforms. SDMS consists of a resident
SCSI BIOS that manages all SCSI controller or processor specific functions,
and a series of SCSI device drivers that provide operating system and
peripheral specific support.

SDMS provides a standard method to interface SCSI I/O subsystems with
devices, operating systems, and application software. It also enhances
system capabilities already provided by SCSI controllers and processors
by facilitating multi-threaded I/O support, system-wide SCSI device access,
and creation of new applications.


******************************** Overview ********************************

An LSI Logic SCSI controller or processor can control peripherals such as
hard disk drives, CD-ROM drives, tape drives, and removable media. SCSI
peripherals are intelligent devices that do not need the constant attention
required by non-intelligent devices. Up to 15 SCSI peripheral devices can
be connected (by using the SCSI bus) to a SCSI host bus adapter card on
which the SCSI controller or processor resides.

A SCSI host bus adapter can also function as a secondary adapter in a system
which already has a primary hard drive controller card (IDE, ESDI, ST506).
Only SCSI host bus adapters will do this, expanding the possibilities for
system configuration.

* SCSI BIOS *

A SCSI BIOS is the bootable ROM code that manages SCSI hardware resources. It
is specific to an LSI Logic family of SCSI controllers or processors. An SDMS
SCSI BIOS integrates with a standard system BIOS, extending the standard disk
service routine provided through INT13h. It is also responsible for processing
and executing SCSI requests communicated from a SCSI device driver or
application.

An important feature of the SCSI BIOS is that it is completely operating
system independent. All ROM-based SCSI BIOS support booting from a SCSI hard
disk and can be ported to a variety of hardware platforms. They also support
16-bit and 32-bit operating systems running under real or protected addressing
modes.

The SDMS SCSI BIOS provides a hardware independent interface which isolates the
operating system drivers and SCSI application programs from the underlying
hardware. This enables a single driver to work with any host adapter or SCSI
controller which has an SDMS SCSI BIOS.

During its boot time initialization, the SCSI BIOS determines if another hard
disk is already installed. If there is, the SCSI BIOS will map any SCSI drives
it finds behind the drive already installed. Otherwise, the SCSI BIOS will
install drives starting with the system boot drive. In this case, the system
will boot from a drive controlled by the SCSI BIOS. For more information on
SCSI BIOS control of hard disk drives, refer to the PCI Storage Device
Management System SDMS 4.0 User's Guide.

* SCSI Device Drivers *

The SCSI device drivers translate an operating system I/O request into a data
structure, and transport the structure to the SCSI BIOS. An LSI Logic SCSI
device driver is operating system specific, but completely hardware
independent. The hardware specifics are addressed by the SCSI BIOS.

Although a driverless solution exists for some operating systems, and
provides adequate support for many applications, loading a driver (or drivers
in some cases) will provide additional features. Connecting peripherals other
than hard disk drives, for example, requires loading the appropriate
driver(s).
