Abstract
Client software stores an identifier corresponding to memory configuration data of interest and causes a software interrupt that requests a memory configuration read function. An interrupt read function handler then reads the data of interest responsive to the identifier and returns the data of interest. The client software may include, for example, BIOS firmware or application software executing in real or protected mode. The memory configuration information may be stored in a hidden I/O or MMIO register device. In such an embodiment, the interrupt handler may enable access to the hidden I/O or MMIO register device prior to reading the data of interest and disable access to the hidden I/O or MMIO register device afterwards.
