The most basic HALs are the "Standard PC" ( hal.dll) and "Advanced Configuration and Power Interface (ACPI) PC" ( halacpi.dll). Windows supports a number of different HALs, and the one that is installed on a machine depends on whether the motherboard/chipset sports a standard programmable interrupt controller (PIC) or the newer advanced PIC (APIC), whether or not it supports the Advanced Configuration and Power Interface (ACPI) specification, and whether or not it has multiple processors.
IRQ assignment and handling is part of the HAL's job. The Hardware Abstraction Layer is a low-level software component through which the operating system communicates with the hardware devices installed in the machine. However, as recently as Mar 2009 we were able to purchase workstations with PCI and ISA slots from Orbit Micro.
ISA devices are very old the ISA bus was no longer included in mainstream PCs manufactured after January 2000. If you plan to use any legacy hardware, particularly any ISA-based devices, then you will have to look even harder for a computer to meet your needs. The current version of RTX (RTX 2011) does not yet support Windows 7 64-bit. Finally, be sure that the 32-bit version of Windows 7 is installed on the system. As the older PCI slot is being phased out in favor of the faster and more versatile PCIe standard, you may have to shop around for a vendor that supplies workstations with PCI. An additional PCI or PCIe will be needed for a second network card if you will integrate Maestro with the EyeLink tracker. You'll need at least two open PCI-Express (PCIe) slots on the motherboard to hold the PCIe-6363 and Intel Gigabit CT network card, plus an open PCI slot for the Detroit C6x (and that slot must conform to PCI specification 2.2 or older the PCI 2.3 and later specs do not allow 5V-only cards like the Detroit).
Ensure the host machine satisfies Maestro's system requirementsĪ minimum 3GHz quad-core processor (Intel i5/i7) is recommended, with 2-4GB RAM.
