I'm using Slacko 5.5, and I have the iso file saved on a USB stick, I want to load everything in RAM and get the USB power by default will not let me
the command that I use is pfix = copy?
from already thank you very much

I've been using puppy off and on for a few years, and now have slacko running full install on an older PC with the Nouveau nvidia driver. It's the first distro I've run on this hardware that did not need a mess of teaking out of the box to get that card to work. Kudos!

Anyway, since this is a discussion on boot options, I've been checking out various posts about speeding up puppy boot time. I saw the emphasis was on hardware detection, and this can be one reason it takes so long to boot for such a comparatively small distro (my time is about 45 seconds, good but not great).

So I was wondering - and I have no idea how difficult this would be - what about a boot option like ubuntu offers to create a profile? The profile would create a file of the drivers actually used in the hardware on the computer, and load those only instead of doing a search at boot time.

This could be automatically disabled on a live disc / usb / what-have-you (since you never know the hardware in such a case). On a frugal install, the profile could be checked first and executed if found.

Just throwing it out there.

Thanks!

I propose to add one option to the boot menu.

"Boot with sfs on current media"

This way when booting starts, puppies wouldn't be looking for all partition, but only on the booting one, which would result in a faster boot.

Subject description: more Linux kernel options than Puppy-specific....
 

A small extract:
Code:
acpi=      [HW,ACPI,X86]
         Advanced Configuration and Power Interface
         Format: { force | off | strict | noirq | rsdt }
         force -- enable ACPI if default was off
         off -- disable ACPI if default was on
         noirq -- do not use ACPI for IRQ routing
         strict -- Be less tolerant of platforms that are not
            strictly ACPI specification compliant.
         rsdt -- prefer RSDT over (default) XSDT
         copy_dsdt -- copy DSDT to memory

         See also Documentation/power/runtime_pm.txt, pci=noacpi


from https://www.kernel.org/doc/Documentation/kernel-parameters.txt

There's heaps more listed there; here's another sample:
Code:
pci=option[,option...]   [PCI] various PCI subsystem options:
      earlydump   [X86] dump PCI config space before the kernel
                 changes anything
      off      [X86] don't probe for the PCI bus
      bios      [X86-32] force use of PCI BIOS, don't access
            the hardware directly. Use this if your machine
            has a non-standard PCI host bridge.
      nobios      [X86-32] disallow use of PCI BIOS, only direct
            hardware access methods are allowed. Use this
            if you experience crashes upon bootup and you
            suspect they are caused by the BIOS.
      conf1      [X86] Force use of PCI Configuration
            Mechanism 1.
      conf2      [X86] Force use of PCI Configuration
            Mechanism 2.
      noaer      [PCIE] If the PCIEAER kernel config parameter is
            enabled, this kernel boot option can be used to
            disable the use of PCIE advanced error reporting.
      nodomains   [PCI] Disable support for multiple PCI
            root domains (aka PCI segments, in ACPI-speak).
      nommconf   [X86] Disable use of MMCONFIG for PCI
            Configuration
      check_enable_amd_mmconf [X86] check for and enable
            properly configured MMIO access to PCI
            config space on AMD family 10h CPU
      nomsi      [MSI] If the PCI_MSI kernel config parameter is
            enabled, this kernel boot option can be used to
            disable the use of MSI interrupts system-wide.
      noioapicquirk   [APIC] Disable all boot interrupt quirks.
            Safety option to keep boot IRQs enabled. This
            should never be necessary.
      ioapicreroute   [APIC] Enable rerouting of boot IRQs to the
            primary IO-APIC for bridges that cannot disable
            boot IRQs. This fixes a source of spurious IRQs
            when the system masks IRQs.
      noioapicreroute   [APIC] Disable workaround that uses the
            boot IRQ equivalent of an IRQ that connects to
            a chipset where boot IRQs cannot be disabled.
            The opposite of ioapicreroute.
      biosirq      [X86-32] Use PCI BIOS calls to get the interrupt
            routing table. These calls are known to be buggy
            on several machines and they hang the machine
            when used, but on other computers it's the only
            way to get the interrupt routing table. Try
            this option if the kernel is unable to allocate
            IRQs or discover secondary PCI buses on your
            motherboard.
      rom      [X86] Assign address space to expansion ROMs.
            Use with caution as certain devices share
            address decoders between ROMs and other
            resources.
      norom      [X86] Do not assign address space to
            expansion ROMs that do not already have
            BIOS assigned address ranges.
      nobar      [X86] Do not assign address space to the
            BARs that weren't assigned by the BIOS.
      irqmask=0xMMMM   [X86] Set a bit mask of IRQs allowed to be
            assigned automatically to PCI devices. You can
            make the kernel exclude IRQs of your ISA cards
            this way.
      pirqaddr=0xAAAAA   [X86] Specify the physical address
            of the PIRQ table (normally generated
            by the BIOS) if it is outside the
            F0000h-100000h range.
      lastbus=N   [X86] Scan all buses thru bus #N. Can be
            useful if the kernel is unable to find your
            secondary buses and you want to tell it
            explicitly which ones they are.
      assign-busses   [X86] Always assign all PCI bus
            numbers ourselves, overriding
            whatever the firmware may have done.
      usepirqmask   [X86] Honor the possible IRQ mask stored
            in the BIOS $PIR table. This is needed on
            some systems with broken BIOSes, notably
            some HP Pavilion N5400 and Omnibook XE3
            notebooks. This will have no effect if ACPI
            IRQ routing is enabled.
      noacpi      [X86] Do not use ACPI for IRQ routing
            or for PCI scanning.
      use_crs      [X86] Use PCI host bridge window information
            from ACPI.  On BIOSes from 2008 or later, this
            is enabled by default.  If you need to use this,
            please report a bug.
      nocrs      [X86] Ignore PCI host bridge windows from ACPI.
                 If you need to use this, please report a bug.
      routeirq   Do IRQ routing for all PCI devices.
            This is normally done in pci_enable_device(),
            so this option is a temporary workaround
            for broken drivers that don't call it.
      skip_isa_align   [X86] do not align io start addr, so can
            handle more pci cards
      firmware   [ARM] Do not re-enumerate the bus but instead
            just use the configuration from the
            bootloader. This is currently used on
            IXP2000 systems where the bus has to be
            configured a certain way for adjunct CPUs.
      noearly      [X86] Don't do any early type 1 scanning.
            This might help on some broken boards which
            machine check when some devices' config space
            is read. But various workarounds are disabled
            and some IOMMU drivers will not work.
      bfsort      Sort PCI devices into breadth-first order.
            This sorting is done to get a device
            order compatible with older (<= 2.4) kernels.
      nobfsort   Don't sort PCI devices into breadth-first order.
      pcie_bus_tune_off   Disable PCIe MPS (Max Payload Size)
            tuning and use the BIOS-configured MPS defaults.
      pcie_bus_safe   Set every device's MPS to the largest value
            supported by all devices below the root complex.
      pcie_bus_perf   Set device MPS to the largest allowable MPS
            based on its parent bus. Also set MRRS (Max
            Read Request Size) to the largest supported
            value (no larger than the MPS that the device
            or bus can support) for best performance.
      pcie_bus_peer2peer   Set every device's MPS to 128B, which
            every device is guaranteed to support. This
            configuration allows peer-to-peer DMA between
            any pair of devices, possibly at the cost of
            reduced performance.  This also guarantees
            that hot-added devices will work.
      cbiosize=nn[KMG]   The fixed amount of bus space which is
            reserved for the CardBus bridge's IO window.
            The default value is 256 bytes.
      cbmemsize=nn[KMG]   The fixed amount of bus space which is
            reserved for the CardBus bridge's memory
            window. The default value is 64 megabytes.
      resource_alignment=
            Format:
            [<order of align>@][<domain>:]<bus>:<slot>.<func>[; ...]
            Specifies alignment and device to reassign
            aligned memory resources.
            If <order of align> is not specified,
            PAGE_SIZE is used as alignment.
            PCI-PCI bridge can be specified, if resource
            windows need to be expanded.
      ecrc=      Enable/disable PCIe ECRC (transaction layer
            end-to-end CRC checking).
            bios: Use BIOS/firmware settings. This is the
            the default.
            off: Turn ECRC off
            on: Turn ECRC on.
      hpiosize=nn[KMG]   The fixed amount of bus space which is
            reserved for hotplug bridge's IO window.
            Default size is 256 bytes.
      hpmemsize=nn[KMG]   The fixed amount of bus space which is
            reserved for hotplug bridge's memory window.
            Default size is 2 megabytes.
      realloc=   Enable/disable reallocating PCI bridge resources
            if allocations done by BIOS are too small to
            accommodate resources required by all child
            devices.
            off: Turn realloc off
            on: Turn realloc on
      realloc      same as realloc=on
      noari      do not use PCIe ARI.
      pcie_scan_all   Scan all possible PCIe devices.  Otherwise we
            only look for one device below a PCIe downstream
            port.
