So, I made a backup, pulled down the boot disks and installed. The install went okay, until I tried to reboot from the hard drive. The kernel loaded okay, but then came the following: ... npx0 on motherboard npx0: INT 16 interface changing root device to sd0a Fatal trap 12: page fault while in kernel mode fault virtual address = 0xf006800 fault code = supervisor read, page not present code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL=0 current process = 0 (swapper) interrupt mask = panic: page fault Please hit reset button Well, I then tried to reinstall, and then noticed that when I brought up Fdisk, it said my geometry was 2810c/4h/94s. I had a hard time convincing it that my geometry was indeed 2800c/4h/94s (as reported by the drive). Finally, I simply installed DOS after which it decided my geometry was 516c/32h/64s, which I could live with. So, I reinstalled, which went fine, and I then tried to boot from the hard drive: ... npx0 on motherboard npx0: INT 16 interface changing root device to sd0a Fatal trap 12: page fault while in kernel mode fault virtual address = 0xefbf7938 fault code = supervisor read, page not present instruction pointer = 0x8:0xf0155b1d code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL=0 current process = 0 (swapper) interrupt mask = panic: page fault So, I am falling back to 2.0R for the meantime. I have a plain-jane 486/33 motherboard with AMIBIOS, AHA1542B w/ two floppies, 3 serial, 1 parallel, and an SMC Elite16. The hard drive I was installing onto is a Conner CFA540S. Let me know if I can be of assistance, Marc. -- I telnetted to whitehouse.gov, and all I got was this lousy .signature!
