Microsoft VirtualPC

Microsoft VirtualPC is going to be one of the very revolutionary and powerful software virtualization. This can allow you to run mulitiple operating systems on ONE box. This VPC baught by MSFT from Connectix, the concept is being enhanced by MS and will eb available for all during fall this year.
I had a chance to install it on my machine and run a couple of images around like Windows Server 2003 with BTS 2004 and also Winodws XP Pro. Could not add that to my office domain due to secrity reason but we can create the netted IP addresses with Virtual Switch for the same. Then you have a network running on your machine. All of the images running on your machien will have same IP Address so it is really confusing but they work well with the DNS names. Even they allow the connectivity on all ports like 139 means I could map the drive to host machine.
The major one I faced in the BIOS for the images, is that the ACPI aware OS option. Yopu have to set this to "YES", trying to figure out why?

What is ACPI?
Newer computers feature ACPI (Advanced Configuration and Power Interface), which extends the APM concept to enable the OS to selectively control power. ACPI supports a variety of power states. Each state represents a different level of power, from fully powered up to completely powered down, with partial levels of power in each intermediate state. Power states include:
Power State Description
S0 - On and fully operational
S1 - System is in low power mode (sleep mode). The CPU clock is stopped, but RAM is powered on and being refreshed.
S2 - Similar to S1, but power is removed from the CPU.
S3 - Suspend to RAM (standby mode). Most components are shutdown. RAM remains operational.
S4 - Suspend to disk (hibernate mode). The memory contents are swapped to the disk drive and then reloaded into RAM when the system is awakened.
S5 Power off

Some newer ACPI aware operating systems, such as Microsoft Windows* 98 SE, Windows Me, Windows 2000 and Windows XP*, only support remote wake-up from standby or hibernate mode (S3 and S4). Remote wake can be initiated by a variety of user selectable packet types and is not limited to the Magic Packet format. For more information about supported packet types, see the operating system settings section.

I will write more when I will find more. But seems like to have the operating system images run better we have to say "YES" in the settings.
