After unistalling Nero on my win98 machine I got the following message on start-up: While Initializing device IOS: ERROR:An I/O subsystem driver failed to load. Either a file in the .\iosubsys subdirectory is corrupt, or the system is low on memory. I have tried deleting the smartdrv file and adding maxfilecache=6144 to the system.ini file. None of which corrected the problem. I have done it with step by step config and the Bootlog file starts to show problems when it trys to load files from the IOSUBSYS dir. Firstly it loads a file called nti4cdr.vxd (which is the only one in that directory, I checked), it then trys to load the files rmm.pdr & bigmem.drv which are not there. Can anyone provide a solution/advice on what to do next?, I really can't lose some of the data/programs i have on this machine. Is there somewhere where I can get a copy of the files that should be in THE IOSUBSYS dir? Any help at all would be fantastic

I'm sure every system is different, but here's what i have in that folder: Acbhlpr.vxd AIC78XX.MPD APIX.VXD ATAPCHNG.VXD BIGMEM.DRV CDFS.VXD cdr4vsd.vxd cdralvsd.BAK CDRALVSD.VXD Cdrpwd.vxd CDTSD.VXD Cdtvsd.vxd Cdudf.vxd Cdudfrw.vxd CDVSD.VXD DISKTSD.VXD DISKVSD.VXD DRVSPACX.VXD ESDI_506.PDR HSFLOP.PDR NECATAPI.VXD PrtSeqRd.vxd PTICACHE.VXD PU66VSD.VXD RMM.PDR SCSI1HLP.VXD SCSIPORT.PDR SMARTVSD.VXD TORISAN3.VXD UdfReadr.vxd ULTRA.MPD VATAPI.VXD VOLTRACK.VXD

First re-install Nero and uninstall it again. After installing go to the control panel and select add/remove software if you did not do this the first time. Select Nero-Burning ROM and Add/Remove. Post Back. Mesich

Thanks for that file list sam. I am now using the BOOTLOG.TXT file to see what files it needs and adding them one a a time mesich, I can't re-instal/remove nero as The PC doesn't make it past the boot stage, thanks for taking the time anyway.
