hello, I'm trying to get FreeBSD (4.1.1R) to boot on an embedded PC. It's a 386ex with 8M RAM, 2 serial ports, and no video. It first boots to embedded DOS on a flash RAM drive (A:), and then runs a small program that loads the first sector off the DiskOnChip drive (C:) and executes it: Loading MBR Relocating 00000000 00007c00 F1 FreeBSD Default: F1 At this point, it beeps after every key press, but never progresses. I gave up and installed the simple "mbr" (using a DiskOnChip evaluation board on a different PC) and tried again. This time the line spins a few times to show it's loading, and then the cursor starts running about the screen. From the hexdump'd output (appended at end of message), it looks like it's just sending escape sequences. The output pauses periodically, just like normal device probing messages. Eventually it hangs, which isn't a big surprise since the disk doesn't have much more than a kernel and some /dev entries. This is especially baffling since the same setup starts booting normally on the test PC. Can anyone tell me what's going on here, or have suggestions to try? --Neil 00000940 4d 42 52 0d 0a 52 65 6c 6f 63 61 74 69 6e 67 0d |MBR..Relocating.| 00000950 0a 30 30 30 30 30 30 30 30 0d 0a 30 30 30 30 37 |.00000000..00007| 00000960 63 30 30 0d 0a 2d 08 5c 08 7c 08 2f 08 2d 08 5c |c00..-.\.|./.-.\| 00000970 08 7c 08 2f 08 2d 08 5c 08 7c 08 2f 08 2d 08 5c |.|./.-.\.|./.-.\| * 000009c0 08 7c 08 2f 08 2d 08 1b 5b 32 35 3b 30 31 48 1b |.|./.-..[25;01H.| 000009d0 5b 32 35 3b 30 32 48 1b 5b 32 35 3b 30 33 48 1b |[25;02H.[25;03H.| 000009e0 5b 32 35 3b 30 34 48 1b 5b 32 35 3b 30 35 48 1b |[25;04H.[25;05H.| 000009f0 5b 32 35 3b 30 36 48 1b 5b 32 35 3b 30 37 48 1b |[25;06H.[25;07H.| 00000a00 5b 32 35 3b 30 38 48 1b 5b 32 35 3b 30 39 48 1b |[25;08H.[25;09H.| 00000a10 5b 32 35 3b 31 30 48 1b 5b 32 35 3b 31 31 48 1b |[25;10H.[25;11H.| 00000a20 5b 32 35 3b 31 32 48 1b 5b 32 35 3b 31 33 48 1b |[25;12H.[25;13H.| 00000a30 5b 32 35 3b 31 34 48 1b 5b 32 35 3b 31 35 48 1b |[25;14H.[25;15H.| 00000a40 5b 32 35 3b 31 36 48 1b 5b 32 35 3b 31 37 48 1b |[25;16H.[25;17H.| 00000a50 5b 32 35 3b 31 38 48 1b 5b 32 35 3b 31 39 48 1b |[25;18H.[25;19H.| 00000a60 5b 32 35 3b 32 30 48 1b 5b 32 35 3b 32 31 48 1b |[25;20H.[25;21H.| 00000a70 5b 32 35 3b 32 32 48 1b 5b 32 35 3b 32 33 48 1b |[25;22H.[25;23H.| 00000a80 5b 32 35 3b 32 34 48 1b 5b 32 35 3b 32 35 48 1b |[25;24H.[25;25H.| 00000a90 5b 32 35 3b 32 36 48 1b 5b 32 35 3b 32 37 48 1b |[25;26H.[25;27H.| 00000aa0 5b 32 35 3b 32 38 48 1b 5b 32 35 3b 32 39 48 1b |[25;28H.[25;29H.| 00000ab0 5b 32 35 3b 33 30 48 1b 5b 32 35 3b 33 31 48 1b |[25;30H.[25;31H.| 00000ac0 5b 32 35 3b 33 32 48 1b 5b 32 35 3b 33 33 48 1b |[25;32H.[25;33H.| 00000ad0 5b 32 35 3b 30 31 48 1b 5b 32 35 3b 30 32 48 1b |[25;01H.[25;02H.| 00000ae0 5b 32 35 3b 30 33 48 1b 5b 32 35 3b 30 34 48 1b |[25;03H.[25;04H.| ...and 5 more pages of similar patterns.
