Talk:PCI Virtual IRQ Assignment in Windows 2000/XP

Having devices on virtual IRQ's is the same as having everything on IRQ 11.

i found with a new PC i setup that i HAD to enable ACPI and APM and do a regular install to get the damn thing to work, and it did so with all devices on a separate IRQ, but in my experience, the best practice is to keep everything separate, as the "feature" of adding the majority of your devices into the one interrupt is rather distasteful, as it can create a world of problems, ranging from minor annoying to greatly upsetting, to throw-computer-down-stairs....

i have apm and acpi enabled on my PC, but i used F5 to install it as a standard PC...

worx fine thanks, much better than having everything on IRQ11

S1(POS) and S3(STR)

S0 Full power (normal operating mode)

S1 Hard drive and monitor shut down when not used

S2 Same as S1, but CPU is also shut off. Equiv to S3, so you may not see S2 mentioned anywhere.

S3 Same as S2, and called Suspend to Ram (STR) or Sleep. RAM contents valid. CPU shut off. +5VSB powers the RAM.

S4 Same as S3, only content of ram are written to disk. Called Hibernate. No power is needed in this state. On reboot, restores the ram from the image stored on disk.

S5 All power off. Full reboot needed ? +5VSB still powers the same circuits powered by the CMOS battery, only the battery is not being drained as long as +5VSB is running. Flipping the switch to OFF on the back of the computer, causes the CMOS to use the coin cell for power, to keep time/date.

 

 

• s0: fully powered on.
• s1: shuts everything off except for cpu, ram, hdd and the mobo, but keeps a low level of power to these devices to maintain sys info.
• s2: ram is powered, cpu is powered but not running, sys info written to ram.
• s3(suspend to ram-STR): shuts off everything except ram, writing all sys info to ram.
• s4(hibernate): writes all sys info to hdd then shuts the computer down completely.
• s5: complete shutdown, no info saved.
