686LCD/S & 686LCD/MG CPU Board - Version 1.4.0 - 8. December 1997 5.2 Memory Map The following table indicates memory map for the 686LCD board. The address ranges specifies the runtime code length. Address Range Length Description Note 00000000-000002FFh 768 Bytes BIOS Interrupt Vector Table 00000300-000003FFh 256 Bytes BIOS Stack Area 00000400-000004FFh 256 Bytes BIOS Data Area 00000500-0009FFFFh 639 KBytes Application Memory. Used by the operating system, device drivers and TSRs 000A0000-000BFFFFh 128 KBytes Video memory page 1 000C0000-000C9FFFh 40 KBytes Video BIOS ROM 1 000CA000-000CE7FFh 18 KBytes Occupied by SCSI BIOS extension if enabled, or the Ethernet 2 BIOS extension if enabled, in the given order. 000CE800-000D27FFh 16KBytes Occupied by Ethernet BIOS extension if both SCSI and Ethernet 2 are enabled. 000D2800-000DFFFFh 54 KBytes Available for external ROM BIOS Extensions 3 000E0000-000EFFFFh 64 KBytes INSIDE Technology BIOS Extension/ AMI System 3 000F0000-000FFFFFh 64 KBytes AMI System BIOS ROM 00100000-1FFFFFFFh 511 MBytes Application Memory. Accessable through EMM-handler or as Extended memory FFFF0000-FFFFFFFFh 64 KBytes AMI System BIOS ROM (mirrored) Note: 1. Used by the on-board VGA controller, if enabled. 2. Location of BIOS are depending on Video BIOS ROM size, e.g. if an external VGA card is used BIOS might be moved due to the PnP manager. 3. Expanded Memory Managers (EMM) may require manual (forced) setting of the location of the EMM page, while some handlers uncritically include the E0000 segment. INSIDE Technology A/S. Page 31 of 134
