SUMMARYWhen you install the driver for the Intel EtherExpress 16 local area network adapter, one of the configuration fields is I/0 Channel Ready. This option can have three possible values: Late, Early, and Never. Typically, Windows NT will only allow the user to set this field to Later or Never. This article includes configuration information for both Windows NT and Windows for Workgroups.
MORE INFORMATIONThe I/O Channel Ready settings optimize the timing of 16-bit data transfers. The Never value forces the card into 8-bit mode; the Late and Early values both allow the card to work in 16-bit mode. The setting that works on most computers is Late, although a few computers require Early to function in 16-bit mode. Some computers will experience problems when the card is set to Early. These problems can range from data loss when transferring large files to computer hangs that require removing the card, transferring it to another computer and using the Softset utility to reset the network adapter.
Windows NTBecause of the potential for serious problems, Windows NT setup does not offer Early as one of the options unless one of the following is true:
Use of the Early setting may cause system failure in some machines. Are you sure you want to continue?While those computers that require Early will not function when the card is set to Late, the EtherExpress driver is capable of detecting this case and it will default the card to Never, which is always safe. Unfortunately, there is no way to detect when Early is not safe without experiencing the problems mentioned above. If you have a computer that requires the Early setting and it is not displayed as an option in Windows NT, you can add Early to the list by doing the following:
Windows for WorkgroupsWhen you install the network adapter and run the Softset utility in Windows for Workgroups, both the Softset and Windows for Workgroups stop responding (hang). If your network adapter has the Early setting and you want to change it to the Late setting:
