The harware configuration is: hardware port irq drq iomem motherboard IBM486SLC n/a n/a n/a n/a CD ROM(panasonic) matcd0 0x320 5 3 default floppy disk fdc0 default default default default hard drive I(maxtor) wdc0 default default default default hard drive II(maxtor) wdc1 default default default default line printer lpt0 default default default default seiral port I sio0 default default default default seiral port II sio1 default default default default we have 2 hard disks, each of 420M, we didnt use lpt0 or sio0, sio1 at all, none of all other devices. This should be a very basic configuration. interesting enough is if we did NOT disable all other unused devices, the installation could process a little furthur, it showed that freebsd tried to build file systems on all partitions(we have /, /usr, /usr/src, /usr/obj, swap, /dos, etc). after it finished building file systems, it tried to copy something to /stand, at this moment, page fault came. However, if we did disable all unused devices, only leave the above 7 devices enabled, the installation would fail immediately, with page fault as the message, i.e, we didnt even see freebsd was trying to build file systems. during installation, we DID see that freebsd recognized the CD ROM. Our harddisk lay out is : for the first harddisk, the first 200M is allocated to DOS, the next 50M or so is for /, the rest(about 170M is for /usr. for the second hard disk, we have swap(32M), /usr/src(recommended cfg), /usr/obj(recommended cfg). Yesterday, we also ran the BIOS ram test, we have 8M ram, all are good. last question: we are wondering what freebsd is trying to do after it finished building up file systems on all partition, 'cause that is the point of failure, it should give us useful hint. thanks for your help, we are looking forward to your reply. qingyan
