Trying your boot.b-mtd it started working but unfortunately command line was garbled (later i found that the turning LARGE_EBDA on was the culprit). Trying to fix it i found, that even if boot loaders themselves were under 0x9a000, the cmdline position didnt depend on LARGE_EBDA. This little patch moves cmdline area to 0x98000 (Dave Miller's recent email to l-k about boot protocol mentions 32k as upper limit for kernel setup code, thus 0x98000 seemed safe). I hope it helps (in case you or someone else see the same problem). Thanks for good work! Regards, Peter PS: I'd suggest mentioning patchin.sh in main README - or at least a pair of words about how it is intended to plug in kernel sources (at least i did it the slower way of directly patching kernel and copying missing files/dirs from mtd to kernel on compilation errors). -- Peter Kundrat peter@kundrat.sk ~ --jRHKVT23PllUwdXP Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="lilo-ebda.patch" diff -ur lilo.orig/lilo.h lilo/lilo.h --- lilo.orig/lilo.h Fri Dec 4 19:55:31 1998 +++ lilo/lilo.h Sun Aug 27 02:40:46 2000 @@ -149,10 +151,12 @@ FIRSTSEG = 0x9A00 STACKSEG = 0x9000 SECONDSEG = 0x9B00 ! second stage loader segment +PARMLINE = 0x2A00 ! parameter line construction area off. #else FIRSTSEG = 0x8A00 STACKSEG = 0x8000 SECONDSEG = 0x8B00 ! second stage loader segment +PARMLINE = 0xD000 ! parameter line construction area off.
