Shown in Figures 3.2 or 3.3). This logic ensures that ROM, RAM and 1/0 devices never simultaneously attempt to place data on the bus! The inputs of the address decoding logic are derived from one, or more, of the address bus lines. The address decoder effectively divides the available memory into blocks corresponding to a particular function (ROM, RAM, I/O, etc.). Hence, where the processor is reading and writing to RAM, for example, the address decoding logic will ensure that only the RAM is.
The RAM that you moved some ribbon cables. These may have blocked the airflow over the RAM or the CPU. 0 Check that when you fitted the RAM that nothing else was disturbed, especially ribbon cables that may have been pulled from their seatings. 0 If the PC gives an unusual number of beeps during bootup, refer to Appendix F. 0 If you see that the contacts on the motherboard are bent or faulty, you may be lucky and have spare sockets you can use.

Defines new higher-density connections; unfortunately SCSI has suffered from a large range of ‘standard‘cables. If you look at hardware suppliers’catalogues, you will see a large range of them! A 32bit bus is defined and is called very wide SCSI but is not in common use. SCSM SCSIJ is yet another extension giving a 20 MHz bus, improved cabling enabling ‘wide’ SCSI (Le. not 8 bit!) and for the first time, SCSIJ contains the new serial SCSI, also called Firewire. There are three different bus.
Reinstall all the software) or use third party software such as Gibson Research’s Spinrite. See grc.com/spinrite.htm To format or reformat the drive, use FORMAT C: /s where the /s parameter means copy the system files in place from sector 0, i.e. make the drive bootable. If you are sure the drive has been formatted, you can try SYS C: which will copy the system to the hard drive. I TIP Do not always believe the manufacturers.
