A2386 Bios Setup

To access the setup either press CTRL+ALT+ESC during boot up, or type BBSETUP at the DOS prompt.


Date	The format is dd.mm.yy (day.month.year)
Time	Sets the bridgeboard real-time clock. The format is hh.mm.ss (hour.minute.seconds) Its a 24 hour clock so remember 3pm = 15.00.00 !!
Diskette 0/1	This corresponds to the floppy drives you have designated through cable connections and jumper settings as A: and B: You must specify the right size of the drive; 720K, 1.4M, NONE, 360K or 1.2M
Hard Disk 0/1	When you select this, the right hand side of the display changes to show a hard disk table. If you are installing a dedicated PC hard disk, you must set the specifications for the drive by choosing a hard disk type from the table. Should be left at NONE for an Autoboot virtual drive, dedicated hard drive or JanusTools partition.
Video	This specifies the default video mode on boot up. Options are: Color 80, MONO, VGA/EGA, Color 40. By default this is set to 80 column colour display. This setting must match your PCPREFS setting for default bridgeboard video mode.
System Speed	This changes the clock speed of the processor. Normally should be left at HIGH to maximize system's performance. Setting it to LOW will half the clock speed (useful when very old PC software doesn't work correctly)
DRAM Wait States	Normally a wait state of 0 is set (no wait states) If slower RAM is added, you may need to change this to 1
Page Mode	Normally should be left at ENABLED to maximize the system's performance by using Page Mode memory. If you need to slow the system down for some reason, you can set this item to disabled. A combination of wait state of 0 and disabled page mode is not supported by the bridgeboard.
On-Board Base Memory	Allows you to set the amount of bridgeboard memory used as base memory, up to a maximum of 640KB.
On-Board Ext Memory	Allows you to set the amount of bridgeboard memory used as extended memory. At least 384K of memory must be available (not used as base memory or expanded memory) to allow shadowing. Any remaining memory may be used as expanded memory.
Off-board Ext	Allows you to set the amount of memory on any AT-compatible RAM cards used as extended memory.
VGA/EGA Shadow	Shadowing allows you to increase your system performance by copying data from ROM to higher speed RAM memory. You should usually leave shadowing enabled to maximize your systems performance. If you have installed a VGA card in one of the Amiga PC expansion slots, you should enable shadowing. If you do not have a VGA card this setting will have no effect on your system.
BIOS Shadow	Shadowing allows you to increase your system performance by copying data from ROM to higher speed RAM memory. You should usually leave shadowing enabled to maximize your systems performance.

Once you have set all the items appropriately, press End to exit the setup utility and save your settings. To abort without saving your changes, press Esc.
