[syslinux] Tr: ISOLINUX failure with Connectix Virtual PC 4.3.2
In fact, I discovered that the bug is caused when there is no primary hard disk image (no hard disk 0). When an HD image is created and attached, ISOLINUX works well: ISOLINUX 1.75 2002-06-14 Copyright (C) 1994-2002 H. Peter Anvin isolinux: Starting up, DL = 99 isolinux: Loaded spec packet OK, drive = 99 isolinux: Sector size appears to be 0800 isolinux: Loading main image from LBA = 0000001C isolinux: Sectors to load = 0004 isolinux: Loaded boot image, verifying... isolinux: Main image read, jumping to main code... isolinux: Root directory at LBA = 00000017 isolinux: isolinux directory at LBA = 00000018 isolinux: About to load config file... isolinux: Configuration file opened...

Peter Anvin isolinux: Starting up, DL = 99 isolinux: Loading spec packet failed, trying to wing it... isolinux: Extremely broken BIOS detected, last ditch attempt with drive = 99 isolinux: Failed to get sector size, assuming 0800 isolinux: Sector size appears to be 0000 isolinux: Loading main image from LBA = 00000CFD isolinux: Sectors to load = 0004 isolinux: Disk error 01, AX = 42FD, drive 99 Boot failed: press a key to retry... This problem doesn't occur with Virtual PC 4.2 and VMWare Workstation 3.1 You can fetch an evaluation version of Connectix Virtual PC at http://www.connectix.com/, this will help you to debug this problem! ----- Fin de message retransmis -----
