Serge,
Thank you for sharing your knowledge with me.
Yes, my machine has more than 15M of RAM. It has 32M byte of RAM.
I have tried what you recommend. I compiled my kernel with the following option now:
device dgb0 at isa? port 0x320 iomem 0xf0000 iosiz ? tty
But I am still having problems. Following is the error messsage
I am having:
dgb0: port 0x320 mem 0xf0000
dgb0: got reset after 0 us
dgb0: PC/Xe 64/8K (windowed)
dgb0 at 0x320-0x323 maddr 0xf0000 msize 8192 on isa
dgb0: internal memory segment 0xf000
dgb0: got reset after 0 us
dgb0: switched to window 0x0
dgb0: switched to window 0x7
dgb0: switched to window 0x7
dgb0: switched to window 0x0
dgb0: wrong code in BIOS at addr 0xc00 : 0x84 instead of 0x28
dgb0: wrong code in BIOS at addr 0xc01 : 0xa9 instead of 0x43
dgb0: wrong code in BIOS at addr 0xc02 : 0x1 instead of 0x29
dgb0: wrong code in BIOS at addr 0xc03 : 0x3c instead of 0x20
dgb0: wrong code in BIOS at addr 0xc04 : 0x15 instead of 0x43
dgb0: 4th memory test (BIOS load) fails
dgb0: switched to window 0x0
dgb0: reset dropped after 0 us
dgb0: switched to window 0x0
dgb0: BIOS download failed
dgb0: Error#(0x2020,0x2020) code=0x2e30
Any idea?
Management is eager to make the DigiBoard working with FreeBSD.
Now, they provide me time and material. So it is the best opportunity
to get the DigiBoard works.
