Hi, I have run into a deadend trying to understand, and troubleshoot this problem. Hence, I would like some pointers. Following is what I did to get my OpenBSD system running, and then subsequently messing it up (in sequence):
(1) Installed OpenBSD/i386 on my Thinkpad X201, and built -current. Did reserve ~140G for Windows, and then installed OpenBSD as described in FAQ. Things were fine for a couple of months. (2) Installed Windows XP ghost image to the first partition. Sadly, ntldr was not installed so machine still booted directly into OpenBSD (3) Installed grub. Here is what /grub/menu.lst looks like: default 0 timeout 5 title Windows XP root (hd0,0) chainloader +1 title OpenBSD root (hd0,1) chainloader +1 (4) grub started fine, and Windows XP boots fine, but when I try to boot OpenBSD, I get something like this: Loading... probing: <<additional details>> disk: fd0 hd0+* >> OpenBSD/i386 BOOT 2.13 open(hd0a:/etc/boot.conf): Invalid argument boot> booting hd0a:/bsd: open hd0a:/bsd: Invalid argument failed(22). will try ... And OpenBSD never boots. I don't recall changing anything else. From what I know (very little), biosboot was able to load the 2nd stage bootloader, but it now failed loading the kernel image. I can boot successfully into OpenBSD using a 4.8 boot CD though. I tried running installboot again (mindlessly!), and get this error: -------------------------- OpenBSD_49$ sudo /usr/mdec/installboot -n -v /boot /usr/mdec/biosboot sd0 Password: boot: /boot proto: /usr/mdec/biosboot device: /dev/rsd0c /boot is 3 blocks x 16384 bytes fs block shift 2; part offset 293603940; inode block 32, offset 10792 master boot record (MBR) at sector 0 partition 0: type 0x07 offset 63 size 293603877 partition 1: type 0xA6 offset 293603940 size 377487360 installboot: invalid location: all of /boot must be < sector 268435455. -------------------------- disklabel reads: -------------------------- OpenBSD_49$ disklabel sd0 # /dev/rsd0c: type: SCSI disk: SCSI disk label: ST9320423AS duid: 93cf9b951f02f209 flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 38913 total sectors: 625142448 boundstart: 0 boundend: 0 drivedata: 0 16 partitions: # size offset fstype [fsize bsize cpg] a: 2104508 293603940 4.2BSD 2048 16384 1 # / b: 8385937 295708448 swap c: 625142448 0 unused d: 41945696 304094400 4.2BSD 2048 16384 1 # /usr e: 4192960 346040096 4.2BSD 2048 16384 1 # /tmp f: 20964832 350233056 4.2BSD 2048 16384 1 # /usr/local g: 4192960 371197888 4.2BSD 2048 16384 1 # /usr/X11R6 h: 125821056 375390848 4.2BSD 2048 16384 1 # /home j: 8385952 501211904 4.2BSD 2048 16384 1 # /var k: 8385920 509597856 4.2BSD 2048 16384 1 # /usr/src l: 12578912 517983776 4.2BSD 2048 16384 1 # /usr/obj OpenBSD_49$ -------------------------- dmesg is ------------------------- OpenBSD 4.9-current (kernel) #5: Wed Mar 23 23:58:17 IST 2011 r...@zimbu.vxindia.veritas.com:/home/amar/site-specific/builds/kernel cpu0: Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz ("GenuineIntel" 686-class) 2.40 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,PCLMUL,MWAIT,DS-CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,SSE4.1,SSE4.2,POPCNT ,AES real mem = 1998659584 (1906MB) avail mem = 1955794944 (1865MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 10/26/10, BIOS32 rev. 0 @ 0xfdbe0, SMBIOS rev. 2.6 @ 0xe0010 (78 entries) bios0: vendor LENOVO version "6QET61WW (1.31 )" date 10/26/2010 bios0: LENOVO 3680LA2 acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SSDT ECDT APIC MCFG HPET ASF!
