Specifies whether the screen displays loading options as CorelCDX is loading.


Share CD-ROM with workgroups
Share CD-ROM with Windows for Workgroups

Specifies whether to permit CD-ROM drive sharing with Windows for Workgroups.


# of open files on all CD-ROMs

Specifies the maximum number of CD-ROM files that can be open at the same time. Each file requires approximately 16 bytes. By default, this value is the same as the value set by the FILES command in your CONFIG.SYS file.


Default CD-ROM drive

Specifies the drive letter, from A to Z, at which CorelCDX starts assigning letters to CD-ROM drives. If the letter you specify isn't available, the next available drive letter is used. By default, CorelCDX begins assigning drive letters from the first unused drive letter. This option is useful for software that requires specific drive letters for CD-ROM drives.


Specifying CorelCDX Memory Options
Setting Memory Options

Configuration defines the default memory options for CorelCDX. The edit panel includes the following information:

•	Expanded Memory Type Used

•	Data Cache Block Size

Additional options define the distribution of cache blocks among CorelCDX's three cache types: path table, directory, and data cache. You can use #CorelCDX Sector Buffers to specify the approximate number of cache buffers allocated, in blocks, for all CDROM drives. By default, 6 cache buffers are allocated.

Alternatively, change the number of cache buffers available for each type of cache:

•	Path Table Cache Blocks

•	Directory Cache Blocks

•	Data Cache Blocks

Minimum, maximum, and alignment requirements may require that the actual number of buffers differ slightly from those you specify.

To modify the CorelCDX memory options

1.	Select CorelCDX Memory Options button from the selection bar.

Or select Memory Options from the CorelCDX menu.

2.	Select the Edit button.

3.	Modify the driver options.

4.	Choose the OK button.


Expanded Memory Type Used

Specifies the expanded memory used for storing code, data, or cache buffers. You can choose one of the following:

•	EMS not used -- no expanded memory is used.

•	Used for code/data only -- loads code and data into expanded memory. Only a small footprint remains resident in conventional memory. This option may be incompatible with some CD-ROM applications; for example, those that perform absolute disk reads into expanded memory buffers.

•	Used for cache buffers only -- loads only cache buffers into expanded memory.

•	Used for code/data and cache buffers -- loads code, data, and cache buffers into expanded memory. In rare cases, this setting may cause problems when you try to read data from a CD-ROM drive. Some applications, when loaded in EMS, may create memory conflicts. If you experience problems, change the value of this option to Used for cache buffers only.

If cache buffers are loaded in expanded memory, a small amount of conventional memory may be allocated to store required tables, and so on. To make the most efficient use of allocated memory, the driver may slightly increase the number of specified cache buffers.


Data Cache Block Size

Specifies the number of 2K sectors assigned to each data cache block. This option is useful for applications that read data from CDs in contiguous segments. By default, the data cache block size is set to 2 sectors. You can specify sector values 1, 2, 4, and 8.

If you set the data cache block size is set to 1, you disable read-ahead caching. However, an additional 4K of conventional memory is required.

Changing the default data cache block size may adversely affect the internal read-ahead caching logic of some CD-ROM drives.


Path Table Cach Blocks
Path Table Cache Blocks

The number of blocks allocated to each path table cache, which store information about the name and location of each directory on the CD. Each path table cache buffer accommodates approximately 100 subdirectories. Path table caches can be set from 2 to 64 blocks. Each block requires 2K.


Directory Cache Blocks

The number of blocks allocated to each directory cache, which stores information such as the name and location of the files in each directory on the CD. Each directory cache buffer accommodates approximately 40 to 50 files. Directory caches can be set from 2 to 64 blocks. Each block requires 2K.


Data Cache Blocks

The number of blocks allocated to each data cache, which stores the contents of recently accessed files from the CD and any data that's expected to be required next. CorelCDX uses a read ahead plus least recently used (LRU) algorithm for its data cache. Data is read into the cache in sector blocks. The data cache can be set from 2 to 64 blocks. The size of each block is determined by the Data cache block size option.


Specifying XMS Parameters
Specifying XMS Cache Parameters

As part of CorelCDX, the Corel CDXCACHE stores information recently read from a CD in extended memory. If an application requests the information again, it is available immediately from cache. Information stored in a cache can be accessed more quickly than re-reading the disc. CDXCACHE is a true LRU (Least Recently Used) cache: frequently used data remains in the cache and infrequently used data is discarded from the cache.

CDXCACHE works best with database type applications, which repeatedly access the same parts of a CD. CDXCACHE can cache up to 16 CD-ROM drives. If your system has more than 16 CD-ROM drives, only the first 16 drives are cached. The page size affects the maximum cacheable sector address.

The cache consists of the module CDXCACHE.BIN, which must be located in the same directory as CORELCDX.COM. CDXCACHE.BIN is automatically loaded when CorelCDX starts.

Configuration defines the following default CDXCACHE cache options:

•	XMS Cache Size

•	XMS read ahead size

•	Max cached size of reads

To modify the CorelCDX XMS cache parameters

1.	Select CorelCDX XMS Cache button from the selection bar.

Or select XMS Cache from the CorelCDX menu.

2.	Select the Edit button.

3.	Modify the driver options.

4.	Choose the OK button.


CorelCDX XMS Cache Size
CorelCDX XMS Size

The size, in kilobytes of the XMS cache. You can choose

•	Disable -- to disable the cache.

•	Default -- to set the cache size to one-quarter of the free XMS memory.

•	Specify -- to set the cache size to a value from 64K to 16384K.


XMS read ahead size

The number of sectors per cache page, which determines the read-ahead operations. You can set this number to 4 or 8. Use the value of 4 for smaller cache sizes; it's more important to cache separate disk reads than to perform read-aheads. Use the value of 8 for larger cache sizes; more data is stored in one operation. The default setting is 4 sectors per cache page.


Max cached size of reads

The maximum size of read requests in sectors that will be cached. The cache performance may improve with larger values. However, the cache may fill up more quickly. The default setting is 4 sectors.


Exiting Configuration

When you exit Configuration, the window closes and the changes you've made to the utilities and drivers are saved.

To exit Configuration

Select Exit from the File menu.


Glossary
Counter

Indicates how many write requests are performed before the contents of the cache buffers are flushed.


Glossary
Tolerance

Specifies the maximum number of consecutive bad sectors allowed in the history mark area on a WORM cartridge when it's mounted. If the cartridge contains more consecutive bad sectors than specified by this value, you can't mount the cartridge.


Glossary
Max Size

Specifies the maximum logical sector size supported by your drives. If you're using drives that support different logical sector sizes, set this value for the largest one. For example, if two drives use a sector size of 1024 bytes and another drive uses a sector size of 2048 bytes, you must set this value to 2048.

The default value for this option is 1024 bytes. Do not change this option unless you're using 2048 bytes cartridges.


Glossary
Device Size

Indicates the storage capacity of the largest WORM cartridge you plan to use.


Glossary
Boot Sector Overwrite

Indicates whether the device driver will allow applications to overwrite the boot sector on cartridges.


Glossary
Verify Method

Indicates the type of data verification performed when information is written to a cartridge. Three methods are available: write verify, verify after write, and disabled.

If you use the write verify method, the device driver always issues a SCSI WRITE VERIFY command when writing data to a cartridge.

Some older drives don't support the WRITE VERIFY command.

If you use the verify after write method, a SCSI WRITE command is followed by a SCSI VERIFY command.

The disabled method writes information to the cartridge without performing any verification. This method is faster than either a write verify or verify after write, but doesn't ensure data integrity.


Glossary
Timer

Specifies the amount of time that the device driver waits after a write request to flush data from its cache buffers to the cartridge. The default is one-third of a second.


Glossary
Buffers

Determines the number of cache buffers allocated for write-once drives. If you aren't using write-once drives, set this option to zero to maximize system performance.


Glossary
Time-Out

Specifies the amount of time that the device driver waits for SCSI commands to complete before failing.


Glossary
Installed Devices

Lists the drive configurations you've previously added to the device driver.


SCSI ID

Indicates the SCSI ID of the drive selected in the Installed Devices list box.


Glossary
SCSI LUN

Indicates the SCSI LUN of the drive selected in the Installed Devices list box.


Glossary
Host Adapter Number

Indicates the number of the host adapter to which the drive selected in the Installed Devices list box is connected.


Glossary
Number of Volumes

Indicates the number of drive letters that you want the device driver to allocate to the device selected in the Installed Devices list box.

The device driver examines write-once and rewritable cartridges to determine the number of drive letters to allocate to the cartridge. If the drive doesn't contain a cartridge, only one drive letter is allocated.

The device driver allocates, by default, one drive letter for each partition on hard drives.


Glossary
Number of Buffers

Indicates the number of cache buffers allocated for each drive supported by the device driver. Each buffer uses 512 bytes. If you've loaded the device driver into EMS, 15K is automatically allocated for cache buffers.


Glossary
Cache Type

Indicates the type of cache used for write-once and rewritable drives. Four cache types are available: read, pass through, default, and enhanced rewritable.

The read cache type uses cache buffers only for reading from the media; data is written directly to the media.

The pass through cache type uses cache buffers for reading and writing data. Data is written to both the cache and the media at the same time, providing a high-level of data security if a system interruption such as a power failure occurs.

The default cache type uses the cache buffers differently for write-once and rewritable drives to provide data security while maximizing performance. Write-once drives use delayed writes; data is written to the cache buffers and then flushed to the cartridge after one-third of a second of inactivity. Rewritable drives use pass through caching. Both write-once and rewritable drives use cache buffers for reading data from the cartridge.

The enhanced rewritable cache type uses delayed writes for both write-once and rewritable drives. This cache type may provide better write performance than the default cache type. However, if a power failure occurs, you may lose all the data in the drive's cache buffers which could cause problems with your disk. For example, when you reboot your system, directories may point to invalid data.


Glossary
Use Expanded Memory

Specifies whether the device driver is loaded into expanded memory, if it's available.


Glossary
Pause after loading driver

Determines whether the system boot pauses after loading the device driver.


Glossary
Output to Screen

Indicates whether the device driver displays configuration information on the screen when loading.


Glossary
Scan all LUNs

Specifies whether the device driver scans the SCSI bus for LUNs.


Glossary
Scan in reverse order
