If you upgrade to Windows 98 and you have a Linksys EtherFast 10/100Mbps network adapter in your computer, you may get the following error message: "Disk write error, unable to write to disk in drive C, data or files may be lost An exception 0E has occurred @ 0028:C0035A67 in vxd ifsmgr (01)." Microsoft officials say your computer will probably lock up after this message. It happens because the network adapter can cause a resource conflict with Windows 98 PCI Steering. You can get your computer back by booting into Safe Mode; going to the Control Panel, System, Device Manager; and removing the network adapter. Of course, this fix will cut you off from your network.
