It's a hodgepodge because some motherboards were designed after large IDE disks came out, others wern't and some people want to use giant IDE disks on old motherboards, others want to use them on new motherboards. The BIOS of the motherboard is responsible for presenting appropriate information about the disk drive to the boot loader. If it presents something weird the boot loader has to make some sense of it in order to find the /kernel file, and if the developer that wrote the boot loader code has never encountered your disk drive/motherboard combo.... Anyway, pardon me for being bigoted, but IDE disks have no place in a UNIX workstation. With supported PCI SCSI adapters as cheap as they are, I for one fail to see why people are willing to trade away gobs of performance for a few extra gigs of hard disk space. If running that 40GB disk drive on IDE is something that just has to be done, then buy a 2GB IDE disk off of Ebay for a few bucks and make it the master, and the mammoth IDE disk the slave. Otherwise, I can tell you the problem is in the boot loader code (I'm sure you already knew that) and anytime you want to experiment on getting it to work, you know where to find the sources! ;-) Ted Mittelstaedt tedm@toybox.placo.com Author of: The FreeBSD Corporate Networker's Guide Book website: http://www.freebsd-corp-net-guide.com > -----Original Message----- > From: owner-freebsd-questions@FreeBSD.ORG > [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of Oscar Ricardo > Silva > Sent: Friday, February 09, 2001 8:53 AM > To: freebsd-questions@FreeBSD.ORG > Subject: Problems installing 4.x on large disks > > > At first I thought I was the only one having problems installing > FreeBSD on > machines with large disks.
