Chapter 2 - BIOS Utility 2-25 2. 8 Date and Time The real-time clock keeps the system date and time. After setting the date and time, you do not need to enter them every time you turn on the system. As long as the internal battery remains good (approximately seven years) and connected, the clock continues to keep the date and time accurately even when the power is off.

Memory/Cache Options Internal Cache(CPU Cache) . . . . . . . . . . . The VGA palette snoop function allows the control palette register (CPR) to manage and update the VGA RAM DAC (Digital Analog Converter, a color data storage) of each VGA card installed in the system. The snooping process lets the CPR send a signal to all the VGA cards so that they can update their individual RAM DACs. The signal goes through the cards continuously until all RAM DAC data has been updated. This allows the display of multiple images on the screen. Some VGA cards have required settings for this feature. Check your VGA card manual before setting this parameter. Altos 500 Series User's Guide Graphics Aperture Size This parameter determines the effective size of the graphics aperture. Graphics aperture is the address range that the AGP video and the CPU use to manage graphical objects. The lowest setting is 8 MB and the highest is 256 MB. Plug and Play OS When this parameter is set to Yes, BIOS initializes only PnP boot devices such as SCSI cards. When set to No, BIOS initializes all PnP boot and non-boot devices such as sound cards. The default setting for most operating systems is No. Reset Resource Assignments Set this parameter to Yes to avoid IRQ conflict when installing non-PnP or PnP ISA cards. This clears all resource assignments and allows BIOS to reassign resources to all installed PnP devices the next time the system boots. After clearing the resource data, the parameter resets to No. Chapter 2 - BIOS Utility 2-33 2. 9. 3 CPU Frequency This parameter displays your CPU's speed and bus frequency. It also allows you to specify the CPU frequency multiplier. [. . . ] Check the disk drive manual for information on setting the SCSI ID for that device. You can also use the SCSISelect utility to determine the SCSI addresses of peripherals on the SCSI bus. Set the SCSI drive to be used as drive D to SCSI ID 1. Check the drive manual for information on setting the SCSI ID for that device. [. . . ]
