Having just completed a 2.2.1-RELEASE installation on an old, abandoned 386 with ESDI drives, and given the number of things that can go wrong, I thought that others might be able to benefit from reading about what worked for me. The system is an Intel 25MHz 80386, Phoenix BIOS version 1.10 04.C1, with 8MB RAM, a WD1007A-WA2 controller, 3.5" floppy, and 2 ESDI drives: a Micropolis 1558-15 and an Imprimis 94166-182, which is now known as a Seagate ST-4182E. Here are the steps that I took which finally led to a successful installation: 1) Configure the hard drives. a. Select 36 Sectors per Track and 512 Bytes per Sector by setting the appropriate jumpers or dip switches on the drive. b. Set both drives to drive address 2. The ESDI command cable in this PC uses has a twist in it to change the last drive on the cable from address 2 to address 1. c. Decide on which drive you want to be Drive 0 (C:), and install the termination resistor. Remove the termination resistor from the other drive. 2) Configure the controller. a. I used the following jumper settings on the WD1007-WA2 (non-default settings are noted): BIOS Address Select W1 1-2 *Note 1 BIOS Address Select W2 2-3 BIOS Shadow RAM W3 No Jumper *Note 2 Floppy Enabled W4 No Jumper Single Spindle Speed W5 No Jumper Floppy Address Select W6 2-3 Floppy Drive Select W7 1-2 WD1007 Mode W8 No Jumper Chassis Ground Disc. W9 No Jumper Input Reg. Unlatched W10 No Jumper Diskette Change Enable W11 Jumper Secondary addr. select W12 No Jumper Floppy Enabled-In Etch W13 Uncut Sector Trans. Enabled W14 Jumper *Note 3 ECC Length Select W15 No Jumper *Note 1: There was a conflict a one point in the installation, which cleared up when I switched the BIOS address. I have not tried switching it back. *Note 2: I felt that FreeBSD doesn't need the Controller BIOS shadowed in RAM since, according to the Handbook, it doesn't use it after booting. *Note 3: According to the Handbook, FreeBSD can't use Sector Translations. 3) Install the drives and controller. Plug the connector at the twisted end of the command cable into Drive 0, the terminated drive. Plug the centre connector into Drive 1. 4) Low-level format. a. Obtain the WDFMT.EXE program. I found it at ftp://shareware.unc.edu/pub/dos/dskutils/wdfmt210.exe. b. Use WDFMT.EXE to low-level format each drive for 35 (not 36!) Sectors per Track and 1:1 Interleave, and with no Alternate Sector or Sector Sparing. I used the following configurations: Micropolis 1558 Imprimis 94166-182 Drive (0/1) 0 1 Cylinders 1224 969 Heads 15 9 Sectors 35 35 Interleave 1 1 Precomp 0 0 Skew 2 2 Alt Sector No No c. Verify each drive. d. Do not enter the Manufacturer Bad Block list. WDFMT.EXE allows only cylinder and head to be entered, so it must be mapping out entire tracks. I left it up to bad144 to find and map out the bad blocks during the FreeBSD installation. e. Do not perform the Surface test. I found that WDFMT.EXE hung after a few seconds. 5) Configure the CMOS drive parameters. The Phoenix BIOS Setup program reserves drive types 48 and 49 for user-defined drive parameters. Set them to the same parameters as the low-level format parameters. I set up the drives as follows: Cyl Hd Pre Lz Sec Hard Disk C: Type 48 1224 15 0 1224 35 Hard Disk D: Type 49 969 9 0 969 35 6) Install FreeBSD. During the FreeBSD installation, when partitioning the drives to allocate disk space for FreeBSD: a. Check that the geometry reported at the top of the screen matches the CMOS drive parameters. b. Create the slice on drive 0 that will contain the root file system so that it resides within the first 1024 cylinders. Since the slice editor doesn't display cylinders, I played it safe by creating a 100MB slice for / and swap, then put the rest of the drive in a second slice for /var and /usr. c. Set Bad Block Scan on each slice! I realize there are probably other configurations that would have worked, but after several false starts I was happy to finally get to the end of the installation and find that the system booted from the hard drive. Thanks to everyone involved in the FreeBSD effort for a such a great product! Regards, ../fam -- Frank A.
