[syslinux] PXELINUX keeppxe mem footprint

[Blaauw,Bernd B.]

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.
