[syslinux] PXELINUX keeppxe mem footprint

[Moore, Patrick J]

I have tried all that (I've been maintaining it for a few years) so I've
tested, and used many of those techniques. I have not yet come across a
single machine for which UMBPCI.SYS can beat "device=\dos\emm386.exe noems
notr h=128 i=b000-b7ff /v".

Without keeppxe I have approx 400K base RAM left after starting the full
redirector. The 90K hit of keeping PXE loaded is just too much. Is there any
way of shunting this to XMS I wonder? The 7K required for keyboard.sys
(loaded high in any case) is pretty insignificant compared to this.

Anyway, as hpa said it is possible to unload PXE but keep UNDI, he just
hasn't implemented it yet.

I have no idea about the unattended-site 's bootdisk, or yours, but at
http://www.nu2.nu/bootdisk/network/ there's a network diskette section.
sorry this turns into an DOS discussion this way, but optimising is very
well possible. for example, replace himem.sys by fdxms.sys (from the FreeDOS
project), and if possible, emm386 by UMBPCI.sys 
http://www.uwe-sieber.de/umbpci_e.html
 
MEM /C /P is your friend in this case..
 
some other things beneficial to you might be replacing command.com by
FreeDOS's one (FreeCOM 0.82patchlevel2), and the kernel by FreeDOS's one
(kernel 2030). However this could have consequences (especially kernel..as
many programs react different to it due to nondocumentend msdos
API's/interrupts etc..)
 
ofcourse the usual LH/DEVICEHIGH stuff is also useful.
