  1. Introduction I/O Addresses The Dreaded Hex IRQs/COM & LPT Ports DMA Legacy Architecture: MCA, ISA, EISA, VESA PCI USB Firewire Installing & Troubleshooting Exp. Cards Expansion Bus Video Notes

  2. Expansion Bus Introduction 1 • The expansion bus is important because…(3 pts) • The expansion bus allows many different types of cards from many different manufacturers to work on any given computer; does that mean all cards have to operate at the speed of the CPU? Expansion Bus? Why? (3pts) • What did IBM do, related to the expansion bus, that was so revolutionary? • Can anyone make a PC? Why? (2 pts) • ISA stands for…

  3. I/O Addresses • I/O Address are the __________________________ ______________________ for devices on the EB. • The address bus discussed in the video is __________ bits wide. • __________ binary numbers are used to represent an address on the bus (How many?). • What’s the “…dreaded hex!

  4. The Dreaded Hex • How many numbers are used in the Hexadecimal system? • Why do we need to use hexadecimal to identify a binary address? • How is it that hexadecimal works so well in converting binary numbers into 8 bit numbers? • What is the I/O “base” address? • The “h” in 03Fh indicates it is a _____________________ number.

  5. IRQs/COM & LPT Ports IRQs • Come up with your own analogy for IRQs. • What happens if you use the same I/O address or IRQ for two different devices? COM and LPT ports • Did Mike make a sexist remark? • Do you think Mike was being serious when he suggested you memorize the COM and LPT port addresses and IRQs? Why? • How can we get away with assigning COM1/COM3 and COM2/COM4 the same IRQs? • You should not change the I/O address or IRQ of a device (T/F). Why? (2 pts)

  6. DMA • Why do you think the industry invented DMA for PCs? • What’s another name for Ultra DMA? • What is Bus Mastering? • A sound card labeled “Ultra” would mean what? • What is Reserved Memory? • What four items are referred to as System Resources?

  7. Legacy Architecture: MCA/ISA/EISA/VESA • What are two significant benefits of MCA • Why did MCA fail? • EISA = 7 MHz, 32 bit, self config. • VL = ____ _____ ___ • What was speed and bit width of VL? • When was VL in use? • What prompted VESA Local Bus? • What were two drawbacks of VESA?

  8. PCI • PCI is an acronym for ______________ ________________ ______________ • Who Created the Bus and Chipset? • What is a Mezzanine bus? • List four specifications for PCI • “Above 15 IRQs” is significant for? • What changed in design regarding Southbridge/Northbridge from early 90s to mid/late 90s? • On a non-ISA MB why do we need IRQs?

  9. USB • USB is an acronym for __________ __________ __________ • How many devices can you control on USB? • How can you add more devices to an Existing USB? • What happens if you do plug in 127 devices? • What is the maximum distance for USB? • List the three connectors for USB • List the speeds for USB 1.1 and USB 2.0

  10. Firewire • How many divices can you connect with Firewire? • What is the maximum distance for Firewire? • What are the speeds for Firewire IEEE 1394 A & B? • What connectors are used with Firewire? • What do you think, does Meyers love firewire/USB

  11. Installing/Troubleshooting Expansion Cards • How should you hold and store card • List two kinds of legacy • What is significant regarding ACPI? • What’s Meyer’s trick regarding device drivers on a floppy? • Which Setting in Resources is the “do it yourself” setting?
