Section 3.3:Sysconfig Information
• Multiple_IO=16, where a setting of 16 allows for multiple sectors per I/O interrupt. When
enabled, this feature reduces operating system overhead by 30-50%. Use with caution.
• EIDE_32BIT=3 enables (E)IDE 32-bit I/O support to an interface card.
• LOOKAHEAD=1 enables drive read-lookahead.
• EXTRA_PARAMS= specifies where extra parameters can be added.
/etc/sysconfig/hwconf
The /etc/sysconfig/hwconf file lists all the hardware that kudzu detected on your system,
as well as the drivers used, vendor ID and device ID information. The kudzu program detects and
configures new and/or changed hardware on a system. The /etc/sysconfig/hwconf file is not
meant to be manually edited. If you do edit it, devices could suddenly show up as being added or
removed.
/etc/sysconfig/i18n
The /etc/sysconfig/i18n file sets the default language, such as:
LANG="en_US"
/etc/sysconfig/init
The /etc/sysconfig/init file controls how the system will appear and function during bootup.
The following values may be used:
• BOOTUP= <value> , where <value> is one of the following:
– BOOTUP=color means the standard color boot display, where the success or failure of de-
vices and services starting up is shown in different colors.
– BOOTUP=verbose means an old style display, which provides more information than purely
a message of success or failure.
– Anything else means a new display, but without ANSI-formatting.
• RES_COL= <value> , where <value> is the number of the column of the screen to start status
labels. Defaults to 60.
• MOVE_TO_COL= <value> , where <value> moves the cursor to the value in the RES_COL
line. Defaults to ANSI sequences output by echo -e.
• SETCOLOR_SUCCESS= <value> , where <value> sets the color to a color indicating success.
Defaults to ANSI sequences output by echo -e, setting the color to green.
