Hi, pxelinux(2.08 or later) waits forever after "boot:" prompt on vmware (4.52). pxelinux(2.07) works. After I comment out DO_IDLE in ui.inc (2.08 or later), it works. but I'm not sure why...

HLT when idle
Hi all, I am wondering about the following suggested change: In isolinux.asm, line 50 (at least in my Debian patched version), add the line "hlt" inside the "DO_IDLE" macro. Explanation: When running isolinux on a vmware box, the boot menu takes up all available CPU. This change seems to solve this problem. I have read elsewhere that such a change will not go in, as the system is set up to perform polling. From looking at the keyboard code, I see no r...
