Two additions to MEMDISK to support OS drivers. The "safe hook" structure ("Safe Master Boot Record INT 13h Hook Routines") is a means for an OS driver to follow a chain of INT 13h hooks, examining the hooks'' vendors and assuming responsibility for hook functionality along the way. For MEMDISK, we guarantee an additional field which holds the physical address for the

H. Peter, three simple commits here[1] (for_hpa branch). Gert, sample binaries are here[2]. --- mdiskchk: Add --no-sequential mode It might be useful to suppress MDISKCHK.COM's classic behaviour of probing all BIOS drive numbers in search of MEMDISKs. Some BIOSes might not enjoy being probed. --- memdisk: Correct El Torito termination response Two

A very special thanks to H. Peter for finding the time to [at least partially, if not wholly] scrutinize and merge the El Torito emulation code for MEMDISK! I'd like to ask that those who've previously used the stale MEMDISK-ISO switch to this latest[1] MEMDISK proper and report any failures. Gert, I believe this version addresses the PloP .ISO trouble you reported. Could you

I read the following about memdisk : .... For any other size, the image is assumed to be a hard disk image, and should typically have an MBR and a partition table. The disk C/H/S geometry is determined by examining the partition table, so the entire image should be partitioned for proper operation. .... I'd like to create a bootable cd, wich boots a linux and some other tools. While

The previous MEMDISK El Torito code merge did not actually work without this.

For anyone wanting to boot an .ISO with MEMDISK: http://git.etherboot.org/?p=people/andytim/syslinux.git;a=shortlog;h=ref s/heads/memdisk-iso NOTE: Your protected-mode OS (Windows, Linux, *BSD) booted from such a MEMDISK will not magically find the MEMDISK image in RAM and use it as a CD without a MEMDISK driver. There are currently 0 MEMDISK drivers in the field, but that might change someday.

Good day to all. Since we've adopted Gary Tong's and Bart Lagerweij's ElTorito.sys (now modified by H. Peter Anvin and tiny changes from myself), I'd appreciate if anyone with more El Torito experience might criticize my comments below and advise as to how they might be wrong. Some of it is off-topic GRUB4DOS detail; safe to ignore. A bit of history: FDUBCD ("FreeDOS

Hi Peter, I'm using isolinux and memdisk to create a multiboot rescue cd for personal use as described on Bart's page (www.nu2.nu). One boot item is to boot DOS 7.1 from Win98SE with a lot of other staff for emergencies. This DOS bootimage puts all necessary stuff into it's own ramdisk (XMSDSK). Some progs on the ramdisk needs access to floppy drive A: and unfortunately I've no

hpa etal, Im trying to get PIRT running on an SBC which has no CD-ROM drive. (an 8 MB ISO which demo's RTAI - RealTime Application Interface, on linux patched with Adeos) (BTW, PIRT uses isolinux) anyway, Im trying to use pxelinux to chainload / memdisk / mboot it, Im having no success. Ive also tried booting memtest86, which I can boot on my laptop using grub, ie title memtest

Hi, I tested this version and it works all right ! Thanks a lot for the quick fix.

Hi... I'm Jaspreet. I've been having the memdisk memory overlapping problems since 2.04 Its always seen in the compressed images whereas the uncompressed images works just fine !!! It just stops at the error "Ran out of input data".. Even the memdisk 2.05 dint solve my problem !!! maybe there r still some bugs remaining. !! My motherboard is Intel 845GEBV2 and i've got

Im trying to boot memtest86 via pxelinux, memdisk, I found this advice on http://forum.x86-secret.com/viewtopic.php?t=2906 folks are making the image match a floppy size by one of the following: dd if=memtest86+-1.xx.bin of=memtest.img bs=360k count=1 conv=sync or dd bs=360k count=1 conv=sync if=memtest86+-1.xx.bin|gzip > memtest.gz I did the former, it did suppress the warning/errors I saw

Hi,, I wud just like to inform that the previous issue of memdisk not booting compressed images still persists !! The release 2.05 that was supposed to fix this issue dint yet solve the problem !!

I'm wondering if it is possible to use memdisk to boot a CD image over the network (using pxelinux) as it is using a floppy or hd image. Anyone tried this? James

I have the same problem. I can not boot a floppy disk. Once I did it but no longer I can do this. I think there is some problem in the new versions of PXELinux. -----Original Message----- From: syslinux-bounces at zytor.com [mailto:syslinux-bounces at zytor.com] On Behalf Of Quinn Plattel Sent: Thursday, September 28, 2006 7:04 PM To: syslinux at zytor.com Subject: Re: [syslinux] problem booting

I have a somewhat unique problem I am trying to solve that requires me to temporarily replace the first 63s of the main hard drive and boot the result. Basically, I am hoping it is possible to modify memdisk to serve requests for the first 63 sectors from a ram disk and pass other requests through to the hard drive. There will never be a read spanning the two, so I don't need it to be able to
