| * | | | Use pxe_call() instead of COMBOOT APIMatt Fleming2012-07-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This involved some other changes, such as passing flags to unload_pxe() now that we only call it from C code, and hence don't need to update KeepPXE. We also needed to move some of the pxe function prototypes to com32/include/syslinux/pxe_api.h because they are now referenced outside of the core.

| * | | | elflink: Replace __intcall() with direct function callsMatt Fleming2012-07-202-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no reason to use the COMBOOT API at all now that we can have any undefined symbols resolved at runtime - we can just access functions directly. Signed-off-by: Matt Fleming <matt.fleming@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The KT_* image types were never meant to be used outside of com32/menu, so use the external image types from syslinux/boot.h Signed-off-by: Matt Fleming <matt.fleming@intel.com>

We need a way to implement DNS resolution so that it works for PXELINUX but returns an error for SYSLINUX/EXTLINUX or ISOLINUX, without introducing undefined symbols. The old COMBOOT API method worked splendidly for this, so revert until someone provides a better solution.

We don't use geometry data returned by 13h/48h, as it can be quite a bit different from the data returned by 13h/08h. disk_write_verify_sector() and disk_write_sector() can deal with more than 1 sector now. Suffix has been renamed to _sectors(). disk_read_sectors() and disk_write_sectors() have been updated to check if we don't overflow bounce buffer, and don't try to read beyond lbacnt. All disk.c functions use 'bps' now, instead of hardcoded SECTOR. struct disk_ebios_dapa - uses packed attribute now. Signed-off-by: Michal Soltys <soltys@ziu.info>

Structure disk_info additionally provides cylinders, besides head and sector. Sanity checks during lba -> chs conversions have been adjusted to use cylinders. CX in cbios read/write code was not calculated properly. Minor signed/unsigned changes. Signed-off-by: Michal Soltys <soltys@ziu.info>

| * | pxe: resolve names via DNS from protected-mode codePaulo Alcantara2012-05-121-2/+2
| |/ | | | | | | | | | | | | | | | | | | | | Syslinux used to call __intcall() for calling routines of the old COMBOOT API to resolve names via DNS (INT 22h, AX=0x0010) that seemed pointless, since INT 22h, AX=0x0010 does call the protected-mode function pm_pxe_resolv_dns() when calling INT 22h, AX=0x0010. So, for resolving names via DNS we must call pxe_dns_resolv() (a protected-mode function) instead for now. Signed-off-by: Paulo Alcantara <pcacjr@zytor.com>

Split the BIOS code into diskio_bios.c so that we don't include any disk BIOS symbols in the EFI executable. This way, the code in core/fs/diskio.c is firmware independent.

Also, move the __syslinux_adv_ptr and __syslinux_adv_size symbols out of ldlinux.c32 and into the core.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We need a firmware-independent way of getting the ipappend strings so add a function pointer to 'struct firmware'. The BIOS backend uses the old __intcall() method whereas the EFI backend accesses 'IPAppends' and 'numIPAppends' directly. Note that the EFI backend currently always returns 0 for 'numIPAppends' because it does not support PXE. Also, while I'm here I fixed the types of 'numIPAppends' and 'IPAppends' for EFI.
