Has anyone had any luck booting from a 4MB diskOnChip using FreeBSD 3.1.0?
Yes, It works fine.
I can boot just fine from a 2MB model.
I get the following error from boot2 when it tries to load loader: Disk error 0x1 (lba=0x1af0)
If I revert back to the 2.2.8 boot2 file I get: 1724 > 1023 (BIOS limit)
Chasing thru the code it would appear that when boot1 uses int13 to read
the drive parameters from bios, they are somehow incorrect. I just need to figure out how to get some I/O out of this assembly code to prove this theory.
I use the bootloader from 3.1-RELEASE. I prepared the DOC2k disk with this script
#!/bin/sh
dd if=/dev/zero of=/dev/rfla0 count=64 fdisk -v -f doc2k4.conf -i fla0 disklabel -w -r fla0 auto disklabel -B -b /boot/boot1 -s /boot/boot2 fla0 newfs /dev/fla0s1c
and doc2k4.conf:
p 1 165 0 7888 a 1
