I get message "No BIOS32 extensions" when booting slackware 2.2.0 - hopeless?

Post by Edward Hartne » Thu, 06 Jun 1996 04:00:00



Hi!

I'm trying to install linux via a CD ROM I got with a web book. The CD
has the slackware 2.2.0 distribution on it. Is this hopelessly out of
date?

When I am booting I get the message:

No BIOS32 extensions installed. This release still depends on
it. Sorry.

This is discouraging!!!!

What should I do?

Thanks!

This message appears when you have compiled a kernel with PCI support
and boot it on a machine that does not contain a pci bus..

It is explained somewhere in the howto..

It does not affect anything!

Unless you have a PCI system, you may ignore this message.

1. getting: "No BIOS32 Extensions"

: #ifndef CONFIG_PCI

#ifdef CONFIG_PCI    <---- not ifndef !

:    if (pcibios_present())
:    { ... }
:     else
:      printk("No BIOS32 extensions present. This release still depends on it."
:            " Sorry.\n");
: #endif

:    I think the intent here is that if CONFIG_SCSI_EATA_DMA was enabled
: in the kernel (during `make config') but CONFIG_PCI was not enabled
: then `pcibios_present()' must succeed (at execution-time) -- i.e., the
: BIOS32 extensions must be present.

Wrong, you copied incorrectly from the source.

It's just the other way. If CONFIG_PCI is not enabled, the whole part is
skipped. If it is enabled and there is no PCIBIOS (BIOS32) in your machine
it complains and also skips the scan.
