    • A system for implementing non-standard I/O adapters in a standardized I/O architecture, the system comprising an I/O hub communicatively coupled to an I/O bus and at least one I/O adapter, the I/O hub including logic for implementing a method, the method comprising receiving a request to perform an operation on the I/O adapter from a requester at a requester address, the I/O adapter at a destination address, determining that the request is in a format other than a format supported by the I/O bus, the I/O bus expecting a requester identifier at a first location in a header of the request, reformatting the request into the format supported by the I/O bus, the reformatting comprising storing the requester address, the destination address and an operation code at the first location in the header of the reformatted request, and sending the reformatted request to the I/O adapter.
    • 一种用于在标准I / O架构中实现非标准I / O适配器的系统,该系统包括通信地耦合到I / O总线和至少一个I / O适配器的I / O集线器,所述I / O集线器包括 用于实现方法的逻辑,所述方法包括从请求者地址的请求者接收对所述I / O适配器执行操作的请求,所述I / O适配器在目的地地址处,确定所述请求是不是 I / O总线支持的格式,I / O总线期望在请求的头部中的第一位置处的请求者标识符,将请求重新格式化为由I / O总线支持的格式,重新格式化包括存储请求者 地址,目的地地址和重新格式化请求的头部中第一个位置的操作代码,并将重新格式化的请求发送到I / O适配器。
