Pros: Good cheap board. Has almost everything I needed (see cons). Installs XP or Vista without needing install disks (fortunately because I don't have a floppy).

Cons: ACPI support is limited: I spent a few days playing with Vista, then XP and couldn't get S3 standby (fans off) to work in either. Turns out, according to Biostar, that they don't support it - only S1 and Hibernate. :-( Vista installed but BSD'd an awful lot. I tried the very latest + beta drivers of everything. The onboard Realtek AC'97 appears to be poorly supported and seems to conflict with either of my two nVidia cards (both gForce 6 series). No such problems in XP.

Overall Review: Biostar were responsive on two counts: first a dead BIOS which Newegg RMA'd (they rock) and second on ACPI issue below. I wish newegg would list ACPI compatibility. Very few manufacturers provide it either.

Pros: Seems to be in working order and has plenty of features. I have managed to make it work with an MSI 64Mb nVidea video card.

Cons: Did not work with the Sapphire ATI X700Pro video card on the PCIExpress x16 slot. The slot is listed on newegg.com and on the asrock.com sites as PCIE x16 but a sticker on the slot says it is "x4" as does the front of the box and the manual. What ever this means (the slot looks x16), I have established that an older nVidea PCIEx16 card does work and the newer ATI card doesn't.
