(The line eater got the beginning of my previous posting. Sorry.) I have added an Everex RAM3000 memory expansion board with 3 Meg to my Hyundai 286C. I would like to have part of this board as a ramdisk for my own uses with the rest as LIM memory for those programs which can take advantage of it. My DOS (MS 3.3) came with an install utility to install a ram disk and/or EMS, but it seems unhappy when I try to do both. What is the difference between the vdisk.sys and ramdrive.sys? Is what I want to do possible? Is installation order crucial? Do the absolute addresses matter? Do I really not understand? (And what about Naomi? - sorry). Please reply direct to me if you feel that this has been re-hashed too many times, or post if you think it's of general interest. Bruce Miller Vacuum tubes aren't dead - they just smell that way.

I use the AEMM.SYS driver to access it. I use the AEX.SYS driver to allocate 1Meg of the expanded memory as extended memory and then make that 1Meg into a ramdisk with RAMDISK.DEV. I use SMARTDRV.SYS to establish a 512K Cache in expanded memory. The remaining 512K of expanded memory is available as expanded memory for whatever program wants to use it. I also allocate the "upper" 384K of the 1Meg on the motherboard as another ramdisk. (I think RAMDRIVE.SYS and SMARTDRV.SYS are from MicroSoft). Here is a fragment of my config.sys. device=C:\DRIVERS\RAMDRIVE.SYS 384 /U device=C:\DRIVERS\AEMM.SYS device=C:\DRIVERS\AEX.SYS 1024 device=C:\DRIVERS\RAMDISK.DEV /M=1024/E/DIR=128 device=C:\DRIVERS\SMARTDRV.SYS 512 /a --- Tom Beattie att!hoqaa!twb t.w.beattie@att.com

Each board vendor should supply the equivalent driver. I believe the AST driver is called REMM??.SYS. I have also used one vendor's driver on a different vendor's board with varying degrees of success. --- Tom Beattie att!hoqaa!twb t.w.beattie@att.com

I don't know why, but vdisk does not work correctly with some combinations of BIOS and expanded memory and/or smartdrive.sys. The best solution is to just use ramdisk instead and forget about vdisk.
