xoroi Posted January 16, 2009 Share Posted January 16, 2009 Hi all! I have 2 HD with 6 partitions. The second HD it's all for Windows and it's in NTFS. The first HD has two boot partitions, on for Windows with NTFS (which is what I had first) and now a second one for OSX. Additionaly, there is a third partitions for music files, which is in FAT32. Everytime I boot and I want to enter the boot options menu in Darwin I get several Ebios read error 0x01 errors. After this I can see the boot options and I can boot normally in either Windows or OSX. But I don't know why I get these errors. Maybe it's because I have Windows with NTFS? The whole system runs OK, except for wifi. So, there are no installation problems or whatever. Thank you for your help Link to comment https://www.insanelymac.com/forum/topic/147277-ebios-read-error-0x01/ Share on other sites More sharing options...

Audiophilip Posted February 2, 2009 Share Posted February 2, 2009 Hi! I'm having the very same problem. It's a SATA drive with GUID partition table, with one HFS+ and a FAT partition. (I'm using the default bootloader coming with iDeneb 1.3.) I also get these "EBIOS read error: Error 0x01" errors only when I try to enter the boot options menu. I'm suspecting some kind of HDD fault, however, Disk Utility verify just passes without any errors. I also noticed a strange behavior after booting into OS X. The FAT partition gets recognized and listed in OS X only after a few minutes of heavy disk usage. All of these symptoms have come after a system reinstall, before everything worked fine. Config: ASUS A8N-E, Athlon 64 3500+, 2G RAM, SATA HDD, Geforce 6600 (256M) iDeneb 1.3 (10.5.5), StageXNU 9.4.0 (Though, I had the same problem with iPC 10.5.6, too.)

ikke5000 Posted February 3, 2009 Share Posted February 3, 2009 i installed a new 1.5tb sata hdd and after putting my osx image to it i get this ebios errors too. funny thing: the errors dont show up when i have only primary partitions on the hdd. i think it has sth to to with partitioning or the bios or bootloader reading the partition table, as when i keep the partition table clean and simple (i.e. no errors shown in partition magic) the errors disappear. partition magic also behaves strange as when i build a partition layout with 3 primarys and one extended with logical volumes it does everything allright but when i reboot and start pqmagic again i have partition table error #110). maybe i try just another bootloader. anyway its a pity that i can just build 4 partitions on this huge drive as this is the max an mbr table allows. edit: just found out if the last logical partition inside the extended partition starts before 1TB ebios error doesn'T show! so i just made the last partition 400GB and all is working. at last i can make more than 4 partitions. regards chris Link to comment https://www.insanelymac.com/forum/topic/147277-ebios-read-error-0x01/#findComment-1067332 Share on other sites More sharing options...
zpkn Posted June 23, 2009 Share Posted June 23, 2009 I know this is an old thread, but for anyone searching these keywords... I used to get the EBIOS Read Error 0x01 when I had drives over 1TB with partitions that started after the 1TB mark. e.g. a 1.5TB drive with 3 partitions - the 1st one 600GB, the 2nd 500GB so the 3rd one begins at the 1.1TB mark. As soon as I made sure no drives had this characteristic, the EBIOS read errors went away, and I can finally use Chameleon 2 RC1 boot options.

I am not sure if iDENEB v1.5.1 is using the Chameleon RC2-r640 or not? I might try the 640 release in case the iDeneb v1.5.1 did not catch the latest build? you would think that it did?

I was having the same reoccurring EBIOS Read Errors on my fresh retail snow leopard install. And the cause was exactly what you said. I had a 1.5Tb drive that had a small partition starting at around 1.2tb. I reordered the partitions and the errors went away. Thanks again!
