From Boyd Faulker I have the following that made his system boot with the ASUS PCI/I-483SP3G board and FreeBSD 950412 SNAP. Still do not under stand why this fixed it, but it did: ] OK. I recompiled the boot floppy kernel numerous times and removing the ] wt0 and mcdX entries allows the probe to continue. I have not unplugged ] my IDE devices, wd0 and wd1. Try doing using the -c option to the boot and disable the st0 and mcd* entries. If this gets you past the hang with your NCR controller let me know ASAP so that I can try to get a real fix for this. I don't have one of the boards here, and they are on back order with my supplier :-(. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Custom computers for FreeBSD
