Getting back to testing with a Lenovo Ideapad 100S-11. Using the February 1 amd64 snapshot I am able to complete the install. Upon first reboot at the initial boot prompt I receive the following messages:
probing: pc0 mem[572K 56L 511M 1391M 61M 9M 2M 124K 36K] disk: hd0* hd1* hd2* >> OpenBSD/amd64 EFIBOOT 3.29 open(hd0a:/etc/boot.conf): invalid argument boot> [enter] cannot open hd0a:/etc/random.seed: invalid argument booting hd0a:/bsd: open hd0a:/bsd: Invalid argument failed(22). will try /bsd I have booted back into the install kernel on a usb drive and can mount the eMMC and verified that the kernel is on sd0a. Rebooting and in the second stage bootstrap again I’ve also issued and ‘ls’ for hd0a, hd1a, and hd2a each of which generated an error. The dmesg from the install kernel is below OpenBSD 5.9 (RAMDISK_CD) #1700: Mon Feb 1 20:07:42 MST 2016 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/RAMDISK_CD RTC BIOS diagnostic error ff<clock_battery,ROM_cksum,config_unit,memory_size,fixed_disk,invalid_time> real mem = 2056638464 (1961MB) avail mem = 1992650752 (1900MB) mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.8 @ 0x7b2ae000 (38 entries) bios0: vendor LENOVO version "E2CN13WW" date 12/22/2015 bios0: LENOVO 80R2 acpi0 at bios0: rev 2 acpi0: tables DSDT FACP UEFI TCPA MSDM UEFI OEM0 DBG2 HPET LPIT APIC MCFG SLIC SSDT SSDT SSDT SSDT SSDT TPM2 SSDT SSDT SSDT FPDT WDAT CSRT BGRT acpimadt0 at acpi0 addr 0xfee00000: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: Intel(R) Atom(TM) CPU Z3735F @ 1.33GHz, 1333.59 MHz cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUS H,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,SSE3,PCLMUL,DTES64,MWAIT,DS-CPL,VMX ,EST,TM2,SSSE3,CX16,xTPR,PDCM,SSE4.1,SSE4.2,MOVBE,POPCNT,DEADLINE,AES,RDRAND, NXE,LONG,LAHF,3DNOWP,PERF,ITSC,SMEP,ERMS,SENSOR,ARAT cpu0: 1MB 64b/line 16-way L2 cache cpu0: apic clock running at 83MHz cpu0: mwait min=64, max=64, C-substates=0.2.0.0.0.0.3.3, IBE cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured ioapic0 at mainbus0: apid 2 pa 0xfec00000, version 20, 87 pins ioapic0: misconfigured as apic 1, remapped to apid 2 acpiprt0 at acpi0: bus 0 (PCI0) acpicpu at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpipwrres at acpi0 not configured acpitz at acpi0 not configured sdhc0 at acpi0: SDHA addr 0x9091d000/0x1000 irq 44 sdmmc0 at sdhc0 sdhc at acpi0 not configured sdhc1 at acpi0: SDHD addr 0x90903000/0x1000 irq 47 sdmmc1 at sdhc1 dwiic0 at acpi0: I2C1, addr 0x90906000 len 0x1000, apic int 32 iic0 at dwiic0 acpibat at acpi0 not configured dwiic1 at acpi0: I2C2, addr 0x9090c000 len 0x1000, apic int 33 iic1 at dwiic1 dwiic2 at acpi0: I2C3, addr 0x9090e000 len 0x1000, apic int 34 iic2 at dwiic2 dwiic2: couldn't find irq for \\_SB_.I2C3.EC01 dwiic3 at acpi0: I2C4, addr 0x90910000 len 0x1000, apic int 35 iic3 at dwiic3 dwiic4 at acpi0: I2C5, addr 0x90912000 len 0x1000, apic int 36 iic4 at dwiic4 acpibat at acpi0 not configured acpibat at acpi0 not configured acpibtn at acpi0 not configured acpiac at acpi0 not configured pci0 at mainbus0 bus 0 pchb0 at pci0 dev 0 function 0 "Intel Bay Trail Host" rev 0x0f "Intel Bay Trail Video" rev 0x0f at pci0 dev 2 function 0 not configured xhci0 at pci0 dev 20 function 0 "Intel Bay Trail xHCI" rev 0x0f: msi usb0 at xhci0: USB revision 3.0 uhub0 at usb0 "Intel xHCI root hub" rev 3.00/1.00 addr 1 "Intel Bay Trail TXE" rev 0x0f at pci0 dev 26 function 0 not configured "Intel Bay Trail LPC" rev 0x0f at pci0 dev 31 function 0 not configured isa0 at mainbus0 com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo efifb0 at mainbus0 wsdisplay0 at efifb0 mux 1: console (std, vt100 emulation) scsibus0 at sdmmc0: 2 targets, initiator 0 sd0 at scsibus0 targ 1 lun 0: <SD/MMC, Drive #01, > SCSI2 0/direct fixed sd0: 29820MB, 512 bytes/sector, 61071360 sectors uhub1 at uhub0 port 1 "vendor 0x1a40 USB 2.0 Hub" rev 2.00/1.11 addr 2 uhub2 at uhub1 port 1 "vendor 0x05e3 USB2.0 Hub" rev 2.00/32.98 addr 3 url0 at uhub2 port 1 "USBKR100 USB 10/100 LAN" rev 1.10/1.00 addr 4 url0: address 00:10:60:e0:ab:4a urlphy0 at url0 phy 0: RTL internal phy uhidev0 at uhub2 port 2 configuration 1 interface 0 "Dell Dell USB Keyboard" rev 1.10/3.50 addr 5 uhidev0: iclass 3/1 ukbd0 at uhidev0 wskbd0 at ukbd0: console keyboard, using wsdisplay0 urtwn0 at uhub2 port 4 configuration 1 interface 0 "Realtek 802.11n WLAN Adapter" rev 2.00/2.00 addr 6 urtwn0: MAC/BB RTL8188CUS, RF 6052 1T1R, address 80:1f:02:f5:26:83 umass0 at uhub1 port 2 configuration 1 interface 0 "Sony Storage Media" rev 2.00/1.00 addr 7 umass0: using SCSI over Bulk-Only scsibus1 at umass0: 2 targets, initiator 0 sd1 at scsibus1 targ 1 lun 0: <Sony, Storage Media, 0100> SCSI0 0/direct removable serial.054c0243A08060519108 sd1: 3824MB, 512 bytes/sector, 7831552 sectors "Bison Corp.
