absmiddle 64MB+ RAM 抓不到

[問題] cming2@ms10.hinet (cming2): Win95 是否抓不到 64MB 以後的 RAM? 我的電腦原本有 64MB RAM, 現在我又加了 64MB,卻只抓到 64MB,多出來的根本沒有抓到,但開機的 RAM test 確定有檢查到 128MB。 [版主] 不要在 Config.sys 掛上 Himem.sys, 有時會造成這種情形. [解答] asoshu.bbs@bbs.cis.nctu.edu.tw (網路小飛俠): 針對 Windows 95 能否上 128 MB 的問題 , 僅將日前自 Microsoft 所得之傳真附上 希望對問題有所幫助. ========================================================================== HIMEM.SYS Cannot Address More Than 64 MB of Memory [MSDOS] ID:Q116256 CREATED: 14-JUN-1994 MODIFIED: 07-MAR-1996 4.x 5.x 6.00 6.20 6.21 6.22 | 3.10 3.11 95 MS-DOS | WINDOWS PUBLIC | kbhw kbtool The information in this article applies to: - Microsoft MS-dos operating system versions 4.x, 5.x, 6.0, 6.2, 6.21, 6.22 - Microsoft Windows operating system versions 3.1, 3.11 - Microsoft Windows 95 SYMPTOMS ======== HIMEM.SYS fails to report or use more than 64 megabytes (MB) of installed memory on computers with an Industry Standard Architecture (ISA) or Micro Channel Architecture (MCA) bus. CAUSE ===== ISA Buses ISA buses lack a standard BIOS interrupt routine for reporting more than 64 MB of memory. HIMEM.SYS depends on the INT 15, function 88 service to determine installed memory, and this function is limited to 65,535 kilobytes (64 MB). MCA Buses MCA-based computers add the INT 15, function C7 service to report installed mwmory. Although this function can report more than 64 MB of memory, HIMEM.SYS has no code to support it. As a result, HIMEM.SYS uses the standard INT 15, function 88 call, which is limited to 64 MB og memory. MORE INFORMATION ================ This limitation does not apply to computers with an Extended Industry Standard Architecture (EISA) bus. On EISA-based computers, HIMEM.SYS scans each slot for device information, which means it can report up to 4 gigabytes (GB). NOTE: Yoou may need to use the /EISA switch on the HIMEM.SYS line in your CONFIG.SYS file.
