Greetings: I have a Mylex AcceleRAID 150 running in a 4.2-RELEASE server and I've run into a couple problems and need some advice. First, the simple one. The 150 came with 4M of memory, and I'm trying to purchase a 16M SIMM from crucial.com (or wherever) to avoid the exorbitant Mylex prices for additional memory. As best as I could determine, the memory is EDO Parity RAM, 36 pin, 60 ns, SIMM. I bought exactly that from Crucial in 16M size (# CT4M36E2M6), but the server will not display or do anything when powered up, even rendering the power toggle functionless. Is there some spec that I'm missing? Second, about 3 out of 5 times, the system fails to boot. It gets to the "press enter to boot [kernel]..." phase, then shows me the slash ( / ), then hangs, again rendering the power toggle functionless, but not the reset switch. I've checked the motherboard and mobo BIOS, and swapped out the RAM, eliminating those as problems. Admittedly, I am running the Mylex Firmware/BIOS that came with the card: Firmware version 4.06-0-29 BIOS 4.10-41 Feb 2, 1999 but I am *highly* reluctant to try and upgrade, as a very competent colleague of mine had not one, but 2 of the same cards get hosed after trying the upgrade and speaking with Mylex tech support. The only other thing I can think that might be relevant to troubleshooting is that both motherboards that I've used have on-board SCSI (and a SCSI CDROM is plugged in and works). Any analysis and suggestions would be very much appreciated, Omar To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
