Forms data is reusable in a first webpage after a user goes to a second webpage, and then returns to the first webpage. After providing access to a first webpage via a portal User Interface (UI) on a display on a client computer, a data entry input of forms data for the first webpage is received from a user of the client computer. The user is then provided access to a second webpage via the portal UI. In response to providing access to the second webpage, the server stores the forms data. In response to the user inputting a request to return to the first webpage from the second webpage, the server creates a populated first webpage by populating the first webpage with the multiple forms data that is stored in the server, and then returns the populated first webpage to the portal UI.

Apparatus and method for providing virtual DMA capability for an adapter card connected to a host system bus with no DMA support. A special interface circuit resides on an adapter card together with a cache data memory. A special software driver resides in the host system. The software driver manages DMA transfers for the application processing circuitry on the adapter card using the cache data memory. The processing circuitry on the adapter card transfers data in and out of the cache data memory as if it had direct memory access to host system memory. In this way, an adapter card for a non-DMA-capable bus, such as the personal computer memory card international association (PCMCIA) bus can act as a bus master.
