Did you have a CDROM in the drive when you booted? If not, that's your problem. There is a known problem with sysinstall and booting without a CD inserted. It won't detect the CDROM drive, because it tries to do an open of all sorts of devices at boot to see if they exist. In any case, changing the bus settle delay won't really help you any, I don't think. The XM-5401B isn't exactly an old device, I don't think, and shouldn't need any longer for a bus settle delay. Assuming you did have a CD in the drive, probably the thing that's taking a while is the read capacity of the CDROM drive, which happens after the bus reset and bus settle delay. I've got a couple of ideas of how to fix this, but none of them are especially "clean".
