As I told Terry via email I have a working 2.0.5-ALPHA system here using
the WD1007 and a Micropolis 1558 ESDI disk.
Here's what I did to make it work:
The WD1007A-WA2 is jumpered like this
W1 2-3 BIOS at C8000-C9FFF
W2 2-3
W3 OUT Disable BIOS and BIOS Shadow RAM
W4 OUT Enable FDC
W5 OUT Single Speed FD
W6 2-3 FDC at 3FX
W7 1-2 Enable FDC
W8 IN WD1005 Mode (Reads Drive Unformatted bytes/sector)
W9 OUT Disconnect Chassis Ground
W10 OUT Unlatch Diag Register
W11 IN Enable Disk Change input
W12 OUT Select Primary Address
W13 IN Enable FDC
W14 IN Disable Sector Translation
W15 OUT 4 Byte ECC
The 1558 is jumpered
RN1 IN Terminator
DA1 OUT
DA2 IN Device 2 ID
DA3 OUT
W5 OUT Spin up at power on
W1 OUT Hard Sectored
W2 IN 36 Sectors/track 578 bytes/sector unformatted
W3 OUT
W4 OUT
This configures the drive to be 1224 cyl 15 head 36 sectors 512 bytes/sector.
The System is a Micronix 386DX20 with Phoenix 386 BIOS 1.10 10
I'm using CMOS type 48 as 1224/15/36
Since I had to disable the 1007 BIOS to use the CMOS drive type, I low level
formated the disk using the WDFMT utility (from www.wdc.com) and turned off
sector sparing. The 1007 BIOS wouldn't let me use 36 sec/track or 1224 cyl.
I ran FDISK and used the entire disk as the primary DOS disk and then
deleted the DOS partition during install. This was just to see the C/H/S
stuff changed.
I had to boot -c to turn off the conflicting devices matcd, ed, ie, and wt
and build a custom kernel once I was done installing.
During install I turned off the newfs -u stuff and used bad144 on each
partition.
It tried to use the entire disk as a FreeBSD partition but was burned
by the >1024 cyl boot problem, so I made two FreeBSD partitions.
The first is for root and swap and the second for /usr.
Here's the boot messages.
