Hello, OpenBSD/amd64 won't boot on my acer aspire 1500. I found that someone had the same problem but I didn't find a solution. The laptop configuration is : Athlon 64 3200+(2 GHz) ; 512 Mo DDR SDRAM 333 ; HD 60 Go ; screen 15" SXGA + ; 802.11g, FireWire, 4USB, 1PC-Card, 1 DVD-RW.
As said, this seems to be the same problem that with the acer aspire 1524wlmi, here is what I've got when I boot : CD-ROM: 9F Loading /4.2/AMD64/CDBOOT probing: pc0 com0 mem[638k 509M a20=on] disk: fd0 hd0+* cd0 >> OpenBSD/amd64 CDBOOT 2.00 boot> booting cd0a:/4.2/amd64/bsd.rd: 2225136+464495+2742160+0+331408 [80 +229320+142471]=0x9dae30 entry point at 0x1001e0 [7205c766, 34000004, 24448612, b2c0a304] So, according to the FAQ, I succesfully load MBR and PBR. The problem occurs when /boot try to load /bsd. You'll notice that unlike what say the FAQ, the boot process doesn't begin with "Loading..." or "Loading;..". I suppose that is simply because this is not the i386 version (I didn't find the same documentation for amd64). I tryed to boot with 3 CD burned from : * CD42.iso from /pub/OpenBSD/4.2/amd64 * install42.iso from /pub/OpenBSD/4.2/amd64 * install42.iso from /pub/OpenBSD/snapshots/amd64 I also tried to boot with -d, -s and -c. I thought at least -c would work, since what I understood was that it enables to change things to load with the kernel. Maybe I just typed something wrong... I wrote "boot -c", at the boot prompt, is it right? Well, finaly, it all results in the same freeze. I tryed to contact the guy who had the (probably) same problem, but it seems the email his no-longer valid, so I can't ask him if he found a solution. So if anyone have any clue of where I should lead my investigations to find what the problem his, and hopefuly resolve it, that's would be very kind to help me.
