[syslinux] Buggy bios, boot of dos image hangs with syslinux, but not with isolinux
Hi We have a couple of FSC Computers here which seem to have a very strange bios. I am trying to boot a MS-DOS disk to flash an Scsi Raid controller. Since the computer doesn't have a floppy anymore I tried syslinux from an usb stick. The menu loads fine but I cannot boot disc images with memdisk on this computer. It works fine on others, of course. But now comes the weird part, if I use the same config with isolinux and boot from cd it works on this computer. I played around with raw, bigraw and safeint but nothing worked. Here is the output: Ramdisk at 0xdbef0000, length 0x002d0000 Disk is floppy 0, 2880K C/H/S = 80/2/36, EDD off Using raw access to high memory Total size needed = 2454 bytes, allocating 3K Old dos memory at 0x9d800 (map says 0x9d800), loading at 0x9cc00 1588: 0xffff 15E801: 0x3c00 0x7cbe INT13 08: Success, count = 0, BPT = 0000:0000 old: int13 = e320aaef int15 = e3200fab new: int13 = 9cc0000a int15 = 9cc0037e Loading boot sector... booting... Starting MS-DOS After that the computer completely freezes, and has to be powered down. Does anybody know of a way around this? Christian

This looks like it may be one of the machines which is helped by the new code. -hpa

Unfortunately it is the same behavior on all of them. But it is only memdisk that is affected by this. If I boot a mini linux distro like DSL or SLAX this works just fine from the usb stick. But than again the memdisk code works if booted from a cd with isolinux. Mighty strange. Christian

But it does not matter how big it is. I tried a couple of standard 1440K and they do not work as well, neither do they work if gzip compressed. But the same images will work from the cd.
