Make a Boot disk with Iomega ZIP Drive Access Do you have Norton Zip Rescue? This utility creates a Rescue disk set using a standard 1.44 Mb floppy disk and a ZIP 100 disk. This disk set actually boots the computer and loads Windows from the ZIP disk. It is a very handy utility to have. As a side effect of that, you can steal drivers from the boot floppy and create your own DOS boot disk that can access an Iomega Zip drive. If you do not have Norton Utilities, you can download a standalone Norton Zip Rescue for free. Download Norton Zip Rescue at http://www.iomega.com/software/featured/nzr.html To make your own boot disk with ZIP 100 support, take a look at the config.sys file on the Norton Zip Rescue boot floppy after creating your rescue set. Note which files are loading and copy them to a bootable floppy disk. Create a similar config.sys file on your boot disk. Here is an example, from a Zip Rescue disk for a PARALLEL PORT EXTERNAL ZIP DRIVE. Please note that if you have anything other than this, you will have to create your own, based on what is loading in the config.sys file. DEVICE=\WINDOWS\HIMEM.SYS DOS=HIGH,UMB DEVICE=\WINDOWS\IFSHLP.SYS DEVICE=\WINDOWS\SETVER.EXE DEVICE=\WINDOWS\DBLBUFF.SYS /D+ LASTDRIVE=Z DEVICEHIGH=ASPIPPM1.SYS FILE=ECR.ILM /SCAN DEVICEHIGH=ASPIPPM1.SYS FILE=NIBBLE.ILM /SCAN /QUIET install DriveLtr.EXE /E: /ZP06 DEVICE=SCSICFG.EXE DEVICEHIGH=SCSIDRVR.SYS set WinComParams= set path=E:\ set ZipDrv=E: set SmartDrvParam=E+ This is straight from my Norton Zip Rescue boot floppy's config.sys file. Yours may be similar, but loading different modules depending on your zip drive type. You may not need all this for your boot disk. I have a parallel port external zip drive, here is the config.sys file that I am using for my own DOS boot disk. Since I don't actually intend to boot windows using this, I have omitted some lines and tailored it to my own environment, loading a real mode IDE CDROM driver. Config.sys File from My Boot Disk: DEVICE=A:\HIMEM.SYS DEVICE=A:\EMM386.EXE NOEMS DOS=HIGH,UMB BUFFERS=15,0 FILES=250 STACKS=9,256 DEVICE=A:\DBLBUFF.SYS /D+ LASTDRIVE=Z DEVICEHIGH=A:\ASPIPPM1.SYS FILE=NIBBLE.ILM install A:\DriveLtr.EXE /X: /ZP06 DEVICE=A:\SCSICFG.EXE DEVICEHIGH=A:\SCSIDRVR.SYS set ZipDrv=X: set SmartDrvParam=X+ DEVICEHIGH=A:\oakcdrom.sys /D:mscd001 Autoexec.bat File from My Boot Disk @ECHO OFF PROMPT $p$g PATH A:\;X:\ LH A:\MSCDEX.EXE /D:mscd001 I took the liberty of making a .zip file that you can download and extract to a bootable disk that has Himem.sys and Emm386.exe copied to it. Instructions are in the ReadMe.txt file within the .zip file ZipBoot.zip. Be sure to read them carefully.
