Is swap mountable?
Hi, Is swap mountable? Such as mount it to /mnt/swap, and then r/w content on it. I'm not trying to use it too much, but as a newbie to OpenBSD world, I really would like to know answer of this. Thanks for your help.
How to add new non-continuous A6 partition after install
Hi, For kinds of reasons, my disk is partitionized like this: 1st partition is for Windows system(Primary) 2nd is for OpenBSD(Primary) 3rd is Windows extended partition(Extended) 4th is originally not used, now I created a new one and mark it as A6.(Primary) Question is after I created the 4th partition, I can get the partition information using fdisk, but can't see anything using disklabel. How do I use the 4th partition? Will it be helpful if I just reformat it to fat32 or ext3? Anybody help? Thanks.
Re: Use memory as disk
Thanks for reply. But still not got it clearly. To get the result of command:grep ramdisk /etc/fstab, ramdisk need to be mounted first. How do I mount ramdisk? I'm using the GENERIC kernel, Do I need to change the config file or rebuild the kernel? I also tried command rdconfig /dev/rd0a 2048, but it reported /dev/rd0a: Device not configured, how to deal with this?

Can ssd of ide interface be recognized?
Hi, I'm planning to use ssd of ide interface, do I need to concern about the driver, or OpenBSD will just use the IDE driver? If anybody has used ssd before, any suggestion, like recommending/rejecting a product? Thanks.

Control noise of harddisk
Hi, BSD4.5 works well on my laptop, but I don't like the noise of the harddisk. Is there a way to lower it? Such as slow the speed or sth? It's ok for me if performance drop down to some extent, because I really don't like that noise. I've tried to use command config -ef /bsd - change wd to 0x8f9 or 0x9f9, but it seems nothing changed. After reboot, when I check the dmesg, it still said wd work in PIO4, DMA 5. And because now I still can't give up XP, when I comes into XP, the hard disk seems much more less noisy. And it seems when I startx or start gnome, the noise come up much more higher. Is this related or it's just my wrong feeling? Any help is appreciated.
Kernel choice
Hi, My computer is Intel two core stuff..., and I used to compile kernel to use original NTFS file system, and I'm using the kernel GENERIC, which is without the .MP, Is it right? Will it have too much effect if I just keep it the same as now? Here's the information I found: When I boot computer, it will display two cpu information; in dmesg, there's one cpu; and with the command sysctl, it said ncput=1, do these matter ? Thanks. The following is my dmesg: OpenBSD 4.5 (kernel) #0: Sun Aug 9 05:25:48 HKT 2009 r...@win7:/wk/other/build/kernel cpu0: Genuine Intel(R) CPU T2130 @ 1.86GHz (GenuineIntel 686-class) 1.87 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,EST,TM2,xTPR real mem = 2137485312 (2038MB) avail mem = 2058539008 (1963MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 02/26/08, BIOS32 rev. 0 @ 0xfd690, SMBIOS rev. 2.4 @ 0xe0010 (67 entries) bios0: vendor LENOVO version 7EETC9WW (2.19 ) date 02/26/2008 bios0: LENOVO 0657LN1 acpi0 at bios0: rev 2 acpi0: tables DSDT FACP SSDT ECDT TCPA APIC MCFG HPET SLIC BOOT SSDT SSDT SSDT SSDT SSDT acpi0: wakeup devices LID_(S3) SLPB(S3) EXP0(S4) EXP1(S4) EXP2(S4) EXP3(S4) PCI1(S4) USB0(S3) USB1(S3) USB2(S3) USB7(S3) HDEF(S4) acpitimer0 at acpi0: 3579545 Hz, 24 bits acpimadt0 at acpi0 addr 0xfee0: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: apic clock running at 133MHz cpu at mainbus0: not configured ioapic0 at mainbus0: apid 1 pa 0xfec0, version 20, 24 pins ioapic0: misconfigured as apic 2, remapped to apid 1 acpihpet0 at acpi0: 14318179 Hz acpiprt0 at acpi0: bus 0 (PCI0) acpiprt1 at acpi0: bus -1 (AGP_) acpiprt2 at acpi0: bus 2 (EXP0) acpiprt3 at acpi0: bus -1 (EXP1) acpiprt4 at acpi0: bus 4 (EXP2) acpiprt5 at acpi0: bus 12 (EXP3) acpiprt6 at acpi0: bus 21 (PCI1) acpiec0 at acpi0 acpicpu0 at acpi0: C3, C2 acpitz0 at acpi0: critical temperature 127 degC acpitz1 at acpi0: critical temperature 98 degC acpibtn0 at acpi0: LID_ acpibtn1 at acpi0: SLPB acpibat0 at acpi0: BAT0 model 92P1141 serial 1625 type LION oem SONY acpibat1 at acpi0: BAT1 not present acpiac0 at acpi0: AC unit online acpithinkpad0 at acpi0 acpivideo at acpi0 not configured acpivideo at acpi0 not configured bios0: ROM list: 0xc/0xea00! 0xcf000/0x1600 0xd0800/0x1000 0xe/0x1 cpu0: unknown Enhanced SpeedStep CPU, msr 0x06150e2806000e28 cpu0: using only highest and lowest power states cpu0: Enhanced SpeedStep 1867 MHz (1340 mV): speeds: 1867, 800 MHz pci0 at mainbus0 bus 0: configuration mode 1 (bios) pchb0 at pci0 dev 0 function 0 Intel 82945GM Host rev 0x03 vga1 at pci0 dev 2 function 0 Intel 82945GM Video rev 0x03 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) intagp0 at vga1 agp0 at intagp0: aperture at 0xd000, size 0x1000 inteldrm0 at vga1: apic 1 int 16 (irq 11) drm0 at inteldrm0 Intel 82945GM Video rev 0x03 at pci0 dev 2 function 1 not configured azalia0 at pci0 dev 27 function 0 Intel 82801GB HD Audio rev 0x02: apic 1 int 17 (irq 11) azalia0: codecs: Analog Devices AD1981HD, Conexant/0x2bfa, using Analog Devices AD1981HD audio0 at azalia0 ppb0 at pci0 dev 28 function 0 Intel 82801GB PCIE rev 0x02: apic 1 int 20 (irq 11) pci1 at ppb0 bus 2 bge0 at pci1 dev 0 function 0 Broadcom BCM5751M rev 0x21, BCM5750 C1 (0x4201): apic 1 int 16 (irq 11), address 00:16:d3:be:27:c3 brgphy0 at bge0 phy 1: BCM5750 10/100/1000baseT PHY, rev. 0 ppb1 at pci0 dev 28 function 2 Intel 82801GB PCIE rev 0x02: apic 1 int 22 (irq 11) pci2 at ppb1 bus 4 ppb2 at pci0 dev 28 function 3 Intel 82801GB PCIE rev 0x02: apic 1 int 23 (irq 11) pci3 at ppb2 bus 12 uhci0 at pci0 dev 29 function 0 Intel 82801GB USB rev 0x02: apic 1 int 16 (irq 11) uhci1 at pci0 dev 29 function 1 Intel 82801GB USB rev 0x02: apic 1 int 17 (irq 11) uhci2 at pci0 dev 29 function 2 Intel 82801GB USB rev 0x02: apic 1 int 18 (irq 11) uhci3 at pci0 dev 29 function 3 Intel 82801GB USB rev 0x02: apic 1 int 19 (irq 11) ehci0 at pci0 dev 29 function 7 Intel 82801GB USB rev 0x02: apic 1 int 19 (irq 11) usb0 at ehci0: USB revision 2.0 uhub0 at usb0 Intel EHCI root hub rev 2.00/1.00 addr 1 ppb3 at pci0 dev 30 function 0 Intel 82801BAM Hub-to-PCI rev 0xe2 pci4 at ppb3 bus 21 cbb0 at pci4 dev 0 function 0 TI PCI1510 CardBus rev 0x00: apic 1 int 16 (irq 11) cardslot0 at cbb0 slot 0 flags 0 cardbus0 at cardslot0: bus 22 device 0 cacheline 0x8, lattimer 0xb0 pcmcia0 at cardslot0 ichpcib0 at pci0 dev 31 function 0 Intel 82801GBM LPC rev 0x02: PM disabled pciide0 at pci0 dev 31 function 2 Intel 82801GBM SATA rev 0x02: DMA, channel 0 wired to compatibility, channel 1 wired to compatibility wd0 at pciide0 channel 0 drive 0: HITACHI HTS541612J9SA00 wd0: 16-sector PIO, LBA48, 114473MB, 234441648 sectors wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 5 atapiscsi0 at pciide0 channel 1 drive 0 scsibus0 at atapiscsi0: 2 targets cd0 at scsibus0 targ 0 lun 0:
