Just a follow-up on the problem of a Supermicro P6DGE taking forever to boot up. I tried several versions of the BIOS with pretty much the same result. Since each reset the configuration (CMOS) memory, there was little issue of an overlooked setting contributing to the slow boot. I tested th

Supermicros (and to a similar degree Tyan) are mostly in the "server class" of motherboards. That apparently means they put a *lot* of self-test code in there somewhere. I've had literally thousands of Supermicro machines of a dozen different types at various times, and they all took an inordinate

For sure. When I quoted the 20 minute post time on new 4U machines earlier, I didn't include the time the four HBAs on those particular machines spent enumerating each one of the 360 drives connected ... only to poop out at the end of the process anyway because it runs out of memory in a fixed data

On the subject of slow booting, perhaps someone can help me with a very annoying case of the slowboots. I've got a dual slot-1 P3 system here--a Supermicro P6DGE, which uses a 440GX chipset and 2GB of registered SDRAM with two 900MHz CPUs. When it finally get around to s booting, it's a great
