Hello,
I have the following goal : built a "diagnOS" floppy with the GRUB on it,
allowing in particular to boot via the network (LAN) from any unknown
PC with a supported PCI NIC.
At the time, if the PCI Bios is good, the function in pci.c `scan_bus'
perform the task, and indeed print what it has found. But, if one has
compiled many NIC drivers in GRUB, since all the NIC entries are tried
the "driver" called is not mandatorily the good one (for example with a
RTL8029 card (ne2k PCI), scan_bus detected it correctly, but this is the
first entry (RTL8139) which is tried).
For the moment I have added a builtin called `probenic' which only calls the
`eth_pci_init' and displays the result of the search [before sending the
patches, do you think this can be useful for others ?]. I want now to modify
the way the drivers are called, mainly by adding an entry in
struct pci_device {
unsigned short vendor, dev_id;
const char *name;
unsigned int membase;
unsigned short ioaddr;
unsigned short devfn;
};
adding a component for the name of the corresponding NIC driver to call.
Problem : what can be the policy, knowing that the majority of the code
comes from Etherboot, and that I need to modify not only GRUB specific files,
but some files originating from Etherboot ?
Are the #ifdef GRUB #endif sufficient to try to have only one source for
both Etherboot and the GRUB ?
TIA
