/etc/sysconfig/firewall
The /etc/sysconfig/firewall file contains various firewall settings. By default, this file (if
created) is empty.
/etc/sysconfig/harddisks
The /etc/sysconfig/harddisks file allows you to tune your hard drive(s). You can also use
/etc/sysconfig/hardiskhd[a-h], to configure parameters for specific drives.
Do not make changes to this file lightly. If you change the default values
stored here, you could corrupt all of the data on your hard drive(s).
The /etc/sysconfig/harddisks file may contain the following:
• USE_DMA=1, where setting this to 1 enables DMA. However, with some chipsets and hard drive
combinations, DMA can cause data corruption. Check with your hard drive documentation or
manufacturer before enabling this.
