But these addresses reflect the actual BIOS address, for L1, and any configuration, such as relative and relocated addresses for external memory that is held locally on the microprocessor chip itself, or on its bus in the case of some earlier chips. adaptec aic-7890 aic-7891 ultra2 scsi

The "L" stands for "Local," by the way, that is, local to the microprocessor. The hard drives are similar because if you look at a hard drive's architecture it is really just adaptec aic-7890 aic-7891 ultra2 scsi microcomputer in its own right, today. That's short for a "module of memory" and there are many historic reasons for this, not the least of which is old core memory, which was in giant cards about 18 inches by two foot, of core "donuts" adaptec aic-7890 aic-7891 ultra2 scsi memory, but, more importantly, because that is the magic size of packet switching itself: 65, bits.

Not bytes, but adaptec aic-7890 aic-7891 ultra2 scsi. This mod, mod 0, is absolutely critical to all computers, regardless of Operating System. It is a hardware definition that cannot be redefined by software without the software first starting from that physical layout. It is the boot mod for all computer systems. It contains first a jump or GO TO type command [otherwise, the computer doesn't know what to do, it can't until it knows something about the hardware].

This points usually to some area where Boot Loader resides [I know some think this is backwards, but it is not. Boot is a jump instruction to the Boot Loader]. After instruction, usually three bytes, are a lot of pointers, jump instructions, some data, some code, and usually the Operating System's identifiers,which in this case means the Pheonix or Award BIOS information from the OEM. adaptec aic-7890 aic-7891 ultra2 scsi

The jump is to the hardware abstraction layer initial routine that either knows motherboard hardware and defines it, or, figures it out. This is done to seriously cut down on hard ware access times. It doesn't matter if you have both L1 and L2, or just one of them, this information will always be stored from 0x through 0xFFFF.

Looking at your Hardware Abstraction Layer above, notice, that every resource is located within that first mod. However, one of these is an adaptec aic-7890 aic-7891 ultra2 scsi board controller and the other is not. Turning either off, in the BIOS, will most likely have very immediate effects. You won't be able to access the controller you turn off when you reboot. If the OS doesn't come up, you know that the one you turned off is the "main" one. If you then reboot and go back into BIOS, re-enable it and turn off the other, it will either reboot to the OS, or, not because the OS is using it also.

We used 16 IRQ bus over 30 years ago! I read some stuff, by Adaptec aic-7890 aic-7891 ultra2 scsi. Wirth at Intel, chief designer for the Intel line, and how he admitted just copying our mainframe design. But we changed that design some time ago to a full bus of IRQ's, at least bit hardwired interrupts! We don't need Plug and Play in mainframes because the number of IRQ's is equal to the size of the bus, whether it's bit, bit, or the esoteric bit buss architecture. I have no idea why AMD and Intel cannot grasp the concept that a bit IRQ bus is so outdated as to require a full architecture redesign of the IRQ bus input width, which should equal the width of the architecture, currently bits. Sometimes, it is harder to teach a new [or young? So, what we wind up with, is a basic hardware vs.

One they haven't been able to see for well over ten years now. It seems quite simple to me, they simply don't have a computer hardware desing engineer, or at least not one who knows the architecture and how it works.
