PC99: "PC99" is officially designated as Microsoft's 1999-2000 Windows Logo program. It is the minimum standard that a PC must meet in order to display a "Designed for Microsoft Windows" sticker.
The specification recognizes a number of categories of PC with somewhat different characteristics -- servers, workstations, office, consumer, entertainment, and mobile PCs: [I think these categories are not mutually exclusive. For example, 'Office' seems to overlap 'workstations' and 'servers' ... sort of.]
- Performance equivalent to a 300MHz, Celeron with 128K L2 cache (it is unclear whether they are talking about the 300A Celeron or a 300 with a motherboard cache). Workstations equivalent to 400MHz with 256K L2. Mobile PCs equivalent to a 233MHz processor with 128K L2.
- 32MB of memory for consumer and mobile machines. 64MB for office machines. 128MB for WorkStations.
- BIOS support for ACPI, USB keyboards, and USB Hubs
- Two USB ports (only one for Portable PCs)
- No ISA slots [you may regard "Designed to run Windows" as a warning if you have ISA cards you wish to use]
- DVD required in entertainment PCs and recommended for office/consumer PCs with "optical media devices". [No clue what this means. The PC needs glasses?]
- 56K V.90 modem on Consumer and Entertainment PCs Also, V.250AT, V.80 and V.253(for voice modems) compliant.
- Win modems acceptable but must be WDM-based.
- NDIS 5.0 miniport Network adapter required on Office PCs and recommended for consumer and entertainment PCs.
- AGP video is recommended
- Monitor DDCS V3L2 compliant.
- MSDOS audio capability is not required
- An Entertainment PC should "offer more capability" than a Consumer PC [No, I am not making this up].
- Docking, and video requirements for mobile PCs clarified.
- Details of video compliance are clarified/specified.
- Formal Specification compliances required for USB, IEEE1394, PC Card, Cardbus, IR, and PCI are identified.
- Requirements for ISDN voice handling, home networking, IT, Cable modem and ADSL devices if present.
- Daisy chained parallel port devices to support PNP and IEEE1284.3 pass thru requirements.
- USB bandwidth requirements imposed.
There are many other requirements and recommendations. The full specification (about a megabyte) is available in several formats on the Intel and Microsoft web sites
