"SiS" chipset. Unfortunately, it has a number of rather nasty
design flaws that can cause severe data corruption under many common
conditions. Say Y here to include code which tries to automatically
- detect and correct the problems under Linux.
- This option also enables access to the secondary IDE ports in some
- CMD640 based systems. This driver will work automatically in PCI
- based systems (most new systems have PCI slots). But if your system
- uses VESA local bus (VLB) instead of PCI, you must also supply a
- kernel boot parameter to enable the CMD640 bugfix/support:
- "ide0=cmd640_vlb" The CMD640 chip is also used on add-in cards by
- Acculogic, and on the "CSA-6400E PCI to IDE controller" that some
- people have. If unsure, say Y.

Advanced Power Management
CONFIG_APM
APM is a BIOS specification for saving power using several different
- techniques. This is mostly useful for battery powered laptops with APM
- compliant BIOSes. Specifically, the time will be reset after a USER
- RESUME operation, the /proc/apm device will provide battery status
- information, and user-space programs will receive notification of APM
- "events" (e.g., battery status change). This driver does not spin down
- disk drives (see hdparm(8) for that); and it doesn't turn off
- VESA-compliant "green" monitors. This driver does not support the TI
- 4000M TravelMate and the ACER 486/DX4/75 because they don't have
- compliant BIOSes. Many "green" desktop machines also don't have
- compliant BIOSes, and this driver will cause those machines to panic
- during the boot phase (typically, these machines are using a data
- segment of 0040, which is reserved for the Linux kernel). If you don't
