[syslinux] Tr: ISOLINUX failure with Connectix Virtual PC 4.3.2

[christian.lestrade at free.fr]

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: isolinux directory at LBA = 00000018
isolinux: About to load config file...
isolinux: Configuration file opened...

Queer bug isn't it?

Hello,

I have discovered an incompatibility between Connectix Virtual PC 4.3.2 and
ISOLINUX 1.75:

when I boot a .iso CD image using Virtual PC 4.3.2 software, I get the following
errors (debug version):

ISOLINUX 1.75 2002-06-14  Copyright (C) 1994-2002 H. 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!
