[syslinux] Re: Booting the "Universal TCP/IP network bootdisk"

[daniel.frommel at hp.com]

In the mean time a strange phenomenon occured.

When booting the mentioned netbootdisk or the standard windows me bootdisk
(which Windows XP generates when formatting an ms-dos disk) the boot
process fail on some mainboards.

Using e.g. an ASUS P4PE-X/TE (Intel 845 chipset, Realtek 8139 networkchip)
both bootdisks work fine.
Using e.g. an ASUS P4P800 (Intel 865 chipset, 3COM 3C940 networkchip) boot
fails with the following output:
---

Invalid system disk
Replace the disk, and then press any key

We use memdisk 3.07 and the latest BIOSes. Any ideas on that ?
