* hdt: Make the menu and cli use the new disk interfacesPierre-Alexandre Meyer2009-08-053-39/+23
| | | | | | | | | The disklib interfaces have changed (errno_disk introduced). Update these changes in hdt (nobody else use them). Misc: fix get_error declaration. Signed-off-by: Pierre-Alexandre Meyer <pierre@mouraf.org>

* disklib: Change read/write interfacePierre-Alexandre Meyer2009-08-058-206/+164
| | | | | | | Get rid of the error pointer and use a errno-like error reporting mechanism. Intent is to make these more like the standard read/write system calls. Signed-off-by: Pierre-Alexandre Meyer <pierre@mouraf.org>

| | | | | | | | | | | | | | | | | | Win98SE DOS apparently hangs if INT 13h, AH=15h returns the capacity in CX:DX for floppies... *unless* EDD is enabled. Confused yet? This patch also adds some more tracing framework. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
| * MEMDISK: additional EDD DPT FieldsMiller, Shao2009-08-021-2/+2

| | | | | | | | | | | | | | | | | | | | Don't write the EDD DPT unless we're actually in EDD mode! Otherwise we end up corrupting memory beyond the defined code. This was the reason 5ca2764460883f5e9a5bd83db00f242ea1272e33 worked, by moving variables out of the corruption zone. Debugged-by: Shao Miller <Shao.Miller@yrdsb.edu.on.ca> Signed-off-by: H.

| | | | | | | | | | | | | | | | | | Some additional fields from the EDD-4 spec. draft for the Device Parameter Table have been added into the structure in setup.c and memdisk.inc. These were added in the hopes of resolving a FreeDOS MEMDISK bug on IBM ThinkPads.

| | | | | | | | | | | | | | | | | | Trivially optimize the old-style graphics by using another level of temporary buffering in bitplane format, thereby enabling the use of rep movsd to write the contents to the screen. This can speed things up substantially in virtualization environments. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | Move a couple of variables away from the EDD data block. Without this change, FreeDOS doesn't boot on Thinkpads. Unfortunately, this should have been a null change, so it is really not clear why this happens. Stack overflows have been ruled out. Probably need to examine the FreeDOS kernel in some detail.

| * memdisk: handle recursive INT 13h invocationH. Peter Anvin2009-07-301-12/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some systems, e.g. a lot of Thinkpads, invoke INT 13h recursively from within the stack itself. This is generally a bad idea as it re-runs any INT 13h hooks (including the ones that DOS installs!), but it should work. Keep a counter of recursive invocations and simply bypass the whole system including the DL shift if the invocation is recursive. With this, MS-DOS boots on a Thinkpad T61. FreeDOS is still broken, though, but apparently in a different manner... Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | On at least ASUS A8N-E, unless *all* registers are restored to pre-PXE status, localboot doesn't work. We were clobbering DS, ESI and EDX when chainloading an NBP, which meant that localboot wouldn't work in the chainloaded NBP. Fix this. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of looking for a string of null bytes at the end of the OACK string, simply abort parsing if we run into a null byte where an option is expected; either we are seeing junk at the end of the packet, or we are hopelessly confused about how to make sense of the rest of the packet -- in either case, ignoring is the "liberal" option.

| | * PXELINUX: handle OACK packets with extra NULs, cleaner TFTP errorsyslinux-3.82-pre5H. Peter Anvin2009-06-082-11/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are apparently TFTP servers in the field which will send OACK packets with extra NUL bytes appended at the end. If we find an OACK packet where the only thing left at some point during processing is NULs, then just consider the packet processed. We have reported all TFTP protocol errors as "tsize required", which is definitely not true anymore. Change error code to 0 (undefined) and the error string to "TFTP error". When this code gets converted to C we'll do better. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

Unfortunately, this did not work together with MENU HIDDEN (which is exactly the case when having a separate ONTIMEOUT command makes the most sense).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Additional stylistic cleanups. Rename "syscall" to "intcall" (we can't call it __intcall without clashing with com32.h); use macros instead of copying variables to different places with only the type being different. Also, only change the rm/pm jump instructions when actually relocating the code. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
